WHO Recommends Two BioNTech-Pfizer Vaccinations Within 4 Weeks
Patients should receive two doses of the BioNTech-Pfizer vaccine within a 21 to 28 day period to protect against Covid-19.
WHO advisers suggested that in exceptional cases a second vaccine could be delayed by two weeks. This could be chosen to give more people the first dose.
The United Kingdom wants to wait up to 12 weeks with the second shot so that more people can get their first vaccination. Denmark decided on Monday for the same reason to wait up to six weeks with the second dose.
The European Medicines Agency (EMA) states that there should be a maximum of 42 days between the first and second dose.
That deadline must be respected to provide full protection, the agency said. This is part of the vaccine’s authorisation in the EU and should be adjusted if the deadline is extended.
