The VSR vaccine prevents serious lower respiratory tract infections like bronchiolitis and pneumonia caused by the respiratory syncytial virus. It is indicated for newborns via maternal vaccination, adults over 18 with risk conditions, and the elderly. Two types are available: Abrysvo for pregnant women and adults, and Arexvy for the elderly.

What is the VSR Vaccine For?

The VSR vaccine prevents serious lower respiratory tract infections caused by the respiratory syncytial virus (RSV). These infections include bronchiolitis and pneumonia, which can be life-threatening in vulnerable populations.

The vaccine stimulates antibody production against RSV subtypes A and B. This protection helps reduce severe outcomes in high-risk groups.

Who Should Get the VSR Vaccine?

Primary Target Groups

The VSR vaccine is indicated for three main groups:

  • Newborns and infants up to 6 months (via maternal vaccination)
  • Adults aged 18-59 with specific risk conditions
  • Elderly people aged 60+, particularly those over 70

Risk Conditions for Adults

For adults aged 18-59, vaccination is recommended for those with:

  • Heart, lung, kidney, or liver diseases
  • Diabetes or obesity
  • Immunosuppression

These conditions increase the risk of serious RSV infection.

Types of VSR Vaccines Available

Two VSR vaccines are currently available:

Abrysvo Vaccine

  • Indicated for pregnant women between weeks 24-36 of pregnancy
  • Also approved for adults over 18 with risk conditions and elderly over 60
  • Contains inactive RSV-A and RSV-B viruses
  • Available through Brazil’s public health system (SUS)

Arexvy Vaccine

  • Specifically approved for elderly populations
  • Recommended for all people over 70 years old

Both vaccines target the same virus but are formulated for different populations.

Vaccination During Pregnancy

Protecting Newborns Through Maternal Vaccination

The Abrysvo vaccine is safe for pregnant women and approved by Anvisa for administration between weeks 24-36 of pregnancy. The Brazilian Ministry of Health and Brazilian Society of Immunizations recommend vaccination from week 28 onward.

How It Works

When administered to pregnant women, the vaccine stimulates antibody production. These antibodies transfer to the fetus through the placenta, providing passive immunity after birth. This approach is crucial since no direct vaccine exists for infants.

The vaccine should not be administered directly to babies.

Vaccination for the Elderly

Age Recommendations

Both Abrysvo and Arexvy vaccines are recommended for elderly populations:

  • All people over 70 in a single dose
  • People aged 50-69 with risk conditions

Special Considerations

Vaccination is particularly important for:

  • Frail or bedridden elderly
  • Residents of long-term care institutions
  • Those with chronic health conditions

The source did not provide details on efficacy differences between the two vaccines in elderly populations.

Where to Get the Vaccine and Dosage Information

Availability

The Abrysvo vaccine is available through Brazil’s public health system (SUS). For other regions or private healthcare options, the source did not provide specific details on locations or global availability.

Dosage Schedule

  • Pregnant women: Single dose during weeks 24-36 of pregnancy
  • Elderly: Single dose recommended by the Brazilian Society of Immunizations

The source did not provide details on booster shots or additional doses for other groups. Always consult healthcare providers for current, location-specific guidance.

Frequently Asked Questions

Who should get the RSV vaccine and at what ages?

The RSV vaccine is indicated for newborns and infants up to 6 months (via maternal vaccination), adults over 18 with risk conditions, and elderly people from 60 years old. It’s specifically recommended for pregnant women between weeks 24-36 and all people over 70.

What are the different types of RSV vaccines available and who are they for?

Two types are available: Abrysvo for pregnant women (weeks 24-36) to protect newborns, and Arexvy for the elderly. Abrysvo can also be given to adults 18-59 with risk conditions and elderly over 60, while both vaccines are recommended for people over 70.

Can babies get the RSV vaccine directly?

No, currently there is no RSV vaccine indicated for babies. Protection for newborns and infants is achieved through maternal vaccination during pregnancy, where antibodies transfer to the baby through the placenta.
