BioNTech’s managing director, Ugur Sahin, admits that there is a risk that the protection provided by the COVID-19 vaccine developed by Pfizer and BioNTech will decrease if the second dose is delayed.
“There is a risk if the second dose is due,” Sahin said.
According to BioNTech’s data, the vaccine begins to provide protection 12 days after administration.
However, this protection could “diminish if the second dose is not given within three or four or six weeks,” Sahin said.
The manufacturer recommends that the second dose of the Pfizer / BioNTech vaccine should be administered after 21 days.
If two doses are given, the vaccine is 95 percent effective, according to clinical trials.
“I have no doubt that the immune system will be strengthened with the second dose whether we give it after three, four or six weeks,” Sahin said.
The Managing Director of BioNTech stipulates, however, that administration of the second dose of the vaccine 21 days after the first dose should be preferred.
Sahin stressed that governments and health care institutions should make their own analysis of the losses and benefits of delaying the second dose of vaccine in order to vaccinate more people with the first dose in less time. Postponing the administration of the second dose of the vaccine is planned, among others United Kingdom.
In Poland, the government from the very beginning of vaccination against COVID-19 creates reserves for people who received the first dose of the vaccine – it receives about half of the vaccines that reach the country every week.
Sahin also announced that in February BioNTech is to have the results of research that will indicate to what extent the Pfizer / BioNTech vaccine protects against asymptomatic coronavirus infection.
