Vaccinations

Essentials

  • Vaccinations aim at the protection of the whole population, a defined risk group or an individual against significant infectious diseases.
  • Complete protection cannot be provided for everybody.
  • A prerequisite for the inclusion of a vaccine in the national immunization programme is that the benefits involved are greater than the potential harms and that the widespread use of the vaccine is cost-effective at the national level.
  • Notice that the national immunization programme described in this article is based on the Finnish programme. Important country-specific differences may apply with regard to e.g. the vaccines included in such a programme, the schedule and target groups of vaccines, as well as the vaccine preparations. While much of the provided information is general, always consult local (national/regional) official policies and instructions as well.
  • Sources for more information on immunization coverage and programmes as well as vaccinations in different countries are available below here.

Schedule

Basic rules

  • Protection as early as possible
  • Immunization is done according to a schedule that causes as few problems as possible (need to consider neutralizing antibodies from the mother, and the child's own immunological maturity).
  • The target of a national immunization programme is to cover the whole population or a defined high-risk part of the population in which vaccination is sufficiently cost-effective.
  • National policies vary, but usually the vaccinations included in the national immunization programme are voluntary and free of charge.

Deviations from the schedule

  • If vaccination series was interrupted, it should be continued, no need to restart.
  • It is hardly worthwhile to shorten the recommended intervals between vaccinations as it usually would weaken the efficacy of the vaccination in short- or long-term.
  • Yet, if the child has clearly passed the recommended age for vaccination, the second dose (or booster) can be given after an interval shorter than usual (does not apply to rotavirus vaccine).
  • The minimum interval between two injections of the same vaccine is usually at least one month.
  • Several vaccinations can be given at the same time.
    • Use different vaccination sites to avoid interference and to recognize local reactions.
  • Vaccines containing inactivated microbes or their purified antigens can be given together with each other or with vaccines containing live attenuated microbes at the same visit or by any schedule in relation to each other.
  • Two injectable vaccines both containing live attenuated microbes should be given at the same visit or at an interval of at least one month.
    • Do not give immunoglobulin simultaneously with MMR, varicella or yellow fever vaccination
      • Vaccine should be given 3 to 4 weeks before immunoglobulin or 6 to 12 weeks after it.

  • The vaccine prevents those HPV infections that most commonly lead to cancer.
  • When given below 15 years of age, the vaccionation series consists of two doses given at an interval of at least 5 months, but the interval may well be a year. If the series is started only at the age of 15, 3 doses are included. The second dose is given not earlier than 1 month after the dose, and the third dose is given no earlier than 5 months after the second dose.
  • In many European countries, Australia, and the United States, the vaccine is included in the national immunization programme for boys as well http://vaccine-schedule.ecdc.europa.eu/Scheduler/ByDisease?SelectedDiseaseId=38&SelectedCountryIdByDisease=-1.

Vaccinations for special groups in the national immunization programme

  • Those at risk are offered vaccination protection against specific diseases tailored to their needs. These vaccinations are also part of the national vaccination programme and are free of charge.

Vaccinations for stem cell transplant recipients

BCG vaccine BCG Vaccine in the Prevention of Tuberculosis, Does the Efficacy of BCG Vaccine Decline with Time?

  • BCG vaccination is recommended for children below 7 years of age if the child
    • lives in the same household as a person who has a history of diagnosed tuberculosis
    • was born in a country with a significant prevalence of tuberculosis
    • lives in the same household as a person born in a country with a significant prevalence of tuberculosis
    • is within one year moving for more than one month to a country with a significant prevalence of tuberculosis
    • lives in the same household as a person who is a frequent and regular visitor to a country with a significant prevalence of tuberculosis.
  • See e.g. http://cdn.who.int/media/docs/default-source/hq-tuberculosis/who_globalhbcliststb_2021-2025_backgrounddocument.pdf for global incidence rates and local guidance on what is considered significant in this context.
  • In some cases a child may benefit from BCG vaccination even if he/she does not belong to any of the risk groups mentioned above. Based on an assessment by the treating doctor, a child under 7 years of age should be offered BCG vaccination also if the child has any other regular and close contact with a person
    • from a country with a significant prevalence of tuberculosis
    • who has contracted tuberculosis
    • who is known to have had a significant exposure to tuberculosis
    • who cares for persons with pulmonary tuberculosis or otherwise has regular and significant occupational exposure to tuberculosis.
  • It is important that a community health nurse at the maternity clinic assesses the need of the expected child for BCG vaccination before the delivery by interviewing the pregnant mother during a follow-up visit. The need for vaccination of a newborn infant may also be assessed at the maternity hospital. After birth, children are screened for severe mixed immunodeficiency (SCID). A child with an abnormal result is not vaccinated.
  • One dose of the vaccine is administered as intradermal injection in the left upper arm.
  • Usually newborn babies are vaccinated but the vaccine may be given to children up to the age of 7 years.
  • When vaccinating a child older than 6 months of age, it must be ensured before vaccination that the child does not have tuberculosis and has not received BCG vaccination. Ruling out tuberculosis Diagnosing Tuberculosis is primarily done by the IGRA test (see local guidance for details). Alternatively, the Mantoux or tuberculin test can be used.
  • Contraindications to BCG vaccination
    • Positive IGRA or Mantoux/tuberculin test.
    • Congenital immunodeficiency or immunodeficiency caused by disease or its treatment, as vaccination may cause severe local or systemic infection
    • The child has tuberculosis.
  • Take also into account
    • the mother's biological medication during pregnancy
    • rules on the timing of administration of live attenuated vaccines.

Hepatitis A and B combination vaccine

  • The hepatitis combination vaccine is given free of charge to the following groups as part of the programme.
    • People with bleeding disorder who are receiving regular treatment
    • Injecting drug users and their close ones, such as family members, live-in partners and sexual partners
    • Men who have sex with men
  • The vaccine can be given to people aged 1 year and over; paediatric preparation for those aged 1-15 years and adult preparation for those aged 16 years and over.
  • The vaccine series consists of 3 doses given at 0, 1 and 6 months. In exceptional circumstances, vaccines can be administered in persons aged 16 years and over at 0, 7 and 21 days, and a 4th dose at 1 year.
  • In high and long term risk individuals, it is recommended to confirm hepatitis B immunity about 2 months after the third dose Vaccines for Preventing Hepatitis B in Health-Care Workers.
  • See article on viral hepatitis Viral Hepatitis.

Hepatitis A vaccine Hepatitis A Immunisation in Persons Not Previously Exposed to Hepatitis A

  • Hepatitis A vaccine is given free of charge as a part of the national programme to the target groups listed below.
    • People with bleeding disorder who are receiving regular treatment
    • Injecting drug users and their close ones, such as family members, live-in partners and sexual partners
    • Men who have sex with men
  • According to current knowledge, two doses of the vaccine provide a life-long protection against hepatitis A. The age of the vaccinee has to be at least 12 months at the time of the first dose. The second dose is given 6-12 months after the first one.

Hepatitis B vaccine Vaccines for Preventing Hepatitis B in Health-Care Workers, Hepatitis B Immunisation in Persons Not Previously Exposed to Hepatitis B or with Unknown Exposure Status

  • For the following groups, hepatitis A and B combination vaccine (see above) can be given instead of the hepatitis B vaccine.
    • People with bleeding disorder who are receiving regular treatment
    • Injecting drug users and their close ones, such as family members, live-in partners and sexual partners
    • Men who have sex with men
  • Hepatitis B vaccine is given free of charge as a part of the national programme to the target groups listed below.
    • Newborn infants of HBsAg carriers (mother or father) at the age of 0, 1, 2 and 12 months. If the mother is a carrier, the child is also given one dose (125 IU) of HB immunoglobulin before the first vaccination Hepatitis B Immunization for Newborn Infants of Hepatitis B Surface Antigen-Positive Mothers.
    • People who are sexual partners or live in the same household with persons with hepatitis B infection or with asymptomatic HBsAg-positive persons
    • Sex workers
    • Students at risk of HBV infection during work placements
    • In the case of needlestick and other blood-borne incidents, where a risk assessment indicates that protection is necessary and the case is not covered by occupational health care Occupational Exposure to Blood and Body Secretions. Victims of sexual offences may also be included in this category.
    • Children under 5 years of age attending a day-care centre with an HBsAg-positive child
    • Children born locally when at least one parent comes from a country where hepatitis B is prevalent
    • Newborn infants whose mother has hepatitis C infection
  • Given at 0, 1 and 6 months, however, to newborn infants and in any case of high-risk exposure at 0, 1, 2 and 12 months. In newborns, make particularly sure that the whole hepatitis B vaccination schedule is completed because an infection in a small child leads to life-long infection in up to 90% of cases. In exceptional cases in people aged 16 years or older the vaccination may be given at 0, 7 and 21 days, and a fourth dose at 1 year.
  • In people at high and long-term risk, hepatitis B immunity should be confirmed approximately 2 months after the third dose.
  • See article Viral hepatitis Viral Hepatitis.

Influenza vaccine Influenza Vaccination in Asthma: Efficacy and Side Effects, Influenza Vaccine for Patients with Chronic Obstructive Pulmonary Disease, Protection Against Influenza after Annually Repeated Vaccination, Vaccines for Preventing Influenza in Healthy Adults, Influenza Vaccines for Preventing Cardiovascular Disease

  • The same inactivated injectable vaccine is used regardless of age. For children aged 2-6 years, also a nasal spray vaccine is available.
  • The efficacy of the vaccine significantly varies from season to season. The protective effect is also influenced by the vaccine product, the age of the vaccinee, underlying diseases and medication. The vaccine can prevent up to 50-80% of influenza cases in children and working-age adults. The effectiveness is weaker in people over 65 years of age. Vaccination reduces the need for hospitalization of elderly people Vaccines for Preventing Influenza in the Elderly.

Vaccines in general use

Adverse effects Adverse Events after Immunisation with Aluminium-Containing Vaccines

  • Some vaccinations cause adverse reactions, the majority of which are mild and self-limiting local reactions. Severe reactions are rare. An anaphylactic reaction is almost the only situation where rapid actions are required.

Local reactions

  • Erythema, swelling, pain, warmth at the site of vaccination are common.
  • Treatment: immobilization of the site of vaccination (e.g. swaddling), cold compress
  • Symptomatic medication (analgesics, antihistamines)
  • Routine prophylactic administration of an analgesic or antipyretic drug is not recommended as it may decrease the immunological response to the vaccine.

Generalized reactions

  • Fever, itching rash, irritability
    • Symptomatic treatment
  • Anaphylactic reaction Anaphylaxis
    1. Adrenaline 1:1 000 (1 mg/ml) i.m. 0.1 ml/10 kg(for an adult 0.5 ml i.m.)
    2. Adequate follow-up

Avoidance, follow-up and compensation of adverse effects

  • Ask about allergy to eggs or vaccine components Hypersensitivity to Drugs.
  • For contraindications see below.
  • Record adverse reactions accurately.
  • Inform health authorities according to local policies when a severe and unexpected adverse reaction is suspected.
  • The associations between vaccinations and adverse reactions are nowadays investigated by combining register data (epidemiological methods). Reporting about individual cases of suspected adverse effects is still an important means of getting information about new suspected adverse reactions (signal detection).
  • Depending on how vaccine related liability issues have been agreed upon, countries have different practices for compensation of adverse effects of vaccines.

Contraindications

  • The following conditions are not contraindications for vaccination:
    • a history of the disease against which the vaccination is aimed at
    • incubation period of an infectious disease
    • an infectious disease with mild symptoms (e.g. rhinitis, otitis media or diarrhoea)
    • antimicrobial medication (typhoid fever is an exception, see local guidance)
    • local glucocorticoids or a small dose of systemic glucocorticoids (for doses, see local guidance)
    • atopic diseases (atopic rhinitis, asthma, dermatitis)
    • dermatites, limited skin infections
    • history of convulsions in the family
    • stable neurological disease
    • Down's syndrome, developmental disability
    • chronic cardiac, liver, lung, or renal disease, rheumatoid arthritis or diabetes
    • neonatal jaundice
    • pre-term infant, small for date
    • malnutrition
    • breast-feeding (yellow fever vaccine is usually not recommended during breastfeeding, see local guidance)
    • pregnancy of the mother (the child of a pregnant woman can be vaccinated).

True contraindications for vaccination

  • True contraindications are very rare. Almost all people can get the vaccines they need. Only very rarely are there situations where the vaccine cannot be given. In most cases, the situation can be resolved by rescheduling the vaccination.
  • An infection with fever: all vaccines
    • Vaccination is given as soon as the patient has recovered.
    • If the vaccination is being given because of an ongoing epidemic, an infection with fever is not a contraindication.
  • Immunodeficiency
    • Vaccination with vaccines containing inactivated microbes and their purified antigens is safe.
    • Vaccines containing live attenuated bacteria or viruses are contraindicated, with a few exceptions.
    • Live attenuated vaccines in HIV infected patients
      • MMR can be given based on an individual assessment
      • BCG vaccination must not be given to any patient with HIV infection, including asymptomatic patients.
  • Severe adverse reaction from an earlier vaccination with the same vaccine
    • Anaphylaxis or shock, encephalitis, encephalopathy, convulsions
    • A disease of the central nervous system without some other known aetiology
      • Requires case-by-case assessment concerning the benefits and possible harms.
    • Febrile convulsions are not a contraindication: provide antipyretics after the vaccination
  • A neurological disorder or disease that is under investigation
    • Consider postponing vaccines.
    • Vaccination must not be done if a progressive CNS disease is suspected.
    • Vaccinations are continued when a diagnosis has been made or the symptoms have stabilized.
  • Pregnancy: vaccinations are not usually recommended, with the exception of situations where pregnancy predisposes to a severe disease (influenza, COVID-19), vaccination of the pregnant mother may provide protection to the newborn (influenza, tetanus, pertussis, COVID-19) or when vaccination is warranted by the epidemiological situation (polio, meningococcus, yellow fever, pertussis, influenza).
    • An accidental MMR or varicella vaccination is not an indication for termination of pregnancy.
  • Hypersensitivity to some vaccine constituent
    • Hypersensitivity to eggs
      • If food containing eggs causes anaphylactic symptoms:
        • vaccines that are produced in fertilised eggs (influenza and yellow fever vaccines) may usually be given safely, but the patient should be monitored for an hour after the vaccination
        • vaccines that are produced in the skin cells of a chick embryo (MMR and TBE vaccines) may be given normally.
    • Mild hypersensitivity to eggs (eggs cause skin or intestinal symptoms): may be vaccinated normally. Allergic symptoms are possible when giving vaccines that are produced in fertilised eggs.
    • Severe hypersensitivity to antimicrobial drugs (a history of systemic symptoms)
      • Neomycin: rabies (depending on preparation) and varicella vaccines. A specialist in allergology decides about MMR vaccine.
