Booster shot recommended after getting Janssen vaccine in Latvia

People having received the single-dose vaccine produced by Johnson & Johnson (Janssen) should regardless receive a second dose, State Council of Immunization (IVP) decided October 14.

IVP head Dace Zavadska explained that vaccination with Janssen, which consists of a single dose, offers lower protection against the delta variant of the Covid-19 virus and would be more likely to lead to symptomatic Covid-19 and the need to hospitalize than the two-dose cycle by other manufacturer vaccines.

Therefore, IVP recommends getting a booster shot of either the Pfizer or Moderna vaccine 8 to 12 weeks after the first shot, regardless of age. The same Janssen vaccine is also acceptable as the booster.

For those who have recovered from Covid-19 and also got a Janssen vaccine, no booster is needed. 

The second vaccine after Janssen is not mandatory but is recommended to provide better protection against the illness.
