Swissmedic, the Swiss Agency for Therapeutic Products, has approved vaccines from manufacturers Moderna, Pfizer/Biontech and Johnson & Johnson for booster vaccinations against coronavirus. The Swiss Committee on Vaccination Issues [Eidgenössische Kommission für Impffragen] (EKIF) made the following recommendations:
Booster vaccination with an mRNA vaccine is recommended for people aged 12 and over, 4 months after completion of basic immunisation.
If possible, the same vaccine as was administered for the basic immunisation (normally the first two vaccinations) should be given for the booster vaccination.
Information about the vaccines
The Comirnaty® vaccine from Pfizer/BioNTech is preferentially recommended for people under 30, but booster vaccination with the Modern vaccine is also possible.
Young people aged between 12 and 17 can only be given the Pfizer/BioNTech vaccine for booster vaccination. The Spikevax® vaccine from manufacturer Moderna or Comirnaty® from Pfizer/BioNTech can be used for all other people aged 18 and over.
People who cannot be given a booster with an mRNA vaccine for medical reasons or who do not want an mRNA vaccine for other reasons can be given the Janssen® vaccine by J&J.
Boosters for pregnant women
Booster vaccination is also recommended for pregnant women from the 2nd trimester and for breastfeeding women.
Booster vaccination following infection with coronavirus
It is recommended that people who have become infected with Covid-19 fewer than 4 months after full basic immunisation receive their booster vaccination 4 months after the infection.
If the Covid-19 infection occurs more than 4 months after full basic immunisation, the infection is considered to be a booster for the immune system. Another booster vaccination is currently not necessary.
Booster vaccination in cases of basic immunisation with Janssen® (Johnson & Johnson)
Booster vaccination with an mRNA vaccine (Pfizer/BioNTech or Moderna) is recommended for people who were vaccinated with the vector vaccine by Janssen. That is provided that this is possible on medical grounds.
People who cannot be given an mRNA vaccine on medical grounds or who refuse to have an mRNA vaccine for their booster for other reasons can be given a booster vaccination with Janssen 2 months after basic immunisation with Janssen.
Who is booster vaccination NOT recommended for?
Booster vaccination is not yet recommended for severely immunocompromised people aged 12 – 15 years. Basic immunisation should instead be achieved with 3 vaccination doses.
Boosters are currently not recommended for people aged 5 – 11 years.
