Booster or second vaccination?
Which corona vaccine offers the best protection?
In view of the increasing number of infections, EU health authorities are now recommending combination vaccinations.
Amsterdam - Vaccinations should stop the fourth wave of corona in Germany as well.
Boosters are also important now to get the immune system back on its toes.
Which vaccine combination is the best for this?
"Mix and Match" - vaccine combos against Corona
"There is evidence that the combination of viral vector vaccines and mRNA vaccines produces good antibody levels against the coronavirus and a higher T-cell response than using the same vaccine - whether in a primary or booster vaccination," share the European Medicines Agency ( EMA) and the European Center for Disease Control (ECDC) in a joint statement on Tuesday. The so-called heterologous therapies are generally well tolerated.
Such an approach "can provide flexibility in terms of vaccination options, particularly to reduce the impact on vaccine adoption if a vaccine is unavailable for any reason," said the EMA and ECDC.
At the same time, they urged people in the EU to get vaccinated as soon as possible.
It is a confirmation of the findings of a large study on vaccine combinations and their effects, which was published this Monday in the journal
The Lancet
.
Study on booster vaccination - which vaccine combination generates the most antibodies
British scientists have investigated various vaccine combinations on behalf of the local government in order to find the best booster.
A full vaccination with Astrazeneca or Biontech / Pfizer, followed by a Moderna vaccine nine weeks later, evoked a better immune response.
The antibody level was highest in these combinations.
The study confirmed the assumption that a combination of a vector and an mRNA vaccine produces a particularly high level of antibodies.

Best booster?
According to the study, all Covid vaccines increase the number of antibodies
However, the authors of the study emphasize that the results describe the antibody response and not the effectiveness of the vaccines in relation to infection or Covid disease.
All of the vaccines examined that increased the number of antibodies.
The booster vaccination - the third dose was also given 10 to 12 weeks after the primary vaccination.
In Germany, the boosters are recommended every five to six months.
The vaccines from Biontech and Moderna are currently being inoculated.
These side effects can occur.
The US vaccine Novavax could soon get approval in the EU.
Many a skeptic is waiting for it, because it is a so-called dead vaccine.
