Can one change of vaccine for the second dose? Here is a question many French wonder, especially those who felt too many adverse effects after the first injection.
In the United Kingdom, mixing vaccines is allowed. Faced with variants spreading throughout the country, the British government has taken all precautions and confirmed - several months ago - using a different vaccine for the second dose was possible. "It is reasonable to offer one dose of the locally available product to complete the schedule", the UK authorities claimed. the government reminided yet it was necessary to try as much as possible to get vaccinated with the same product for both doses.
As for WHO, they have not stated on the matter. "Clinical trials in some countries are looking at whether you can have a first dose from one vaccine and a second dose from a different vaccine. There isn't enough data yet to recommend this type of combination", it reads on the website.
In France, the Haute Autorité de Santé does allow the change of vaccine on one ground only. People under 55 years of age who have been given a first dose with AstraZeneca will receive Pfizer or Moderna vaccines for their second injections.
The others must stick to the vaccination plan: the first and second injections must be completed with the same product.
Some French have complained about too strong adverse effects and asked to change of vaccine. This ground is not valid, according to health authorities. "It is common to feel a few mild to moderate side effects after being given a vaccine. These are signs stating one's body is creating protection", Vaccination info service website reads.
Créteil Henri-Mondor Hospital head of clinical immunology and infectious disease unit Jean-Daniel Lelièvre intends to reassure anxious people and reminds on France Info that "AstraZeneca is a very good vaccine although it is less effective against some variants. But once you are vaccinated, you are first protected against the seriousness of the infection".
