“I have no reason to doubt these figures”

Britain aims to complete “tens of millions” of vaccinations against Covid-19 over the next three months, British Prime Minister Boris Johnson said on Sunday.

Speaking to the BBC, Johnson said: ‘We hope we can make tens of millions [of Covid-19 vaccines] in the next three months, I can certainly give you that figure, ”he added.

Johnson said the strategy was based on three vaccines, the Pfizer / BioNTech vaccine and the Oxford / AstraZeneca vaccines – both of which have been approved in the UK – and the Moderna vaccine which would be ready for use “soon”.

The Prime Minister, echoing what he said in October last year, said: “I thought in the spring things would be better. I stick to that.

Asked about the number of doses of the Oxford / AstraZeneca Covid-19 vaccine, which was approved by UK regulators on Wednesday, Johnson said 530,000 doses would be ready for inoculation on Monday, in addition to the ‘million or so’ Pfizer / BioNTechCovid – 19 vaccine already distributed.

Earlier on Sunday, UK Health Secretary Matt Hancock said on Twitter that the country had administered 1 million Pfizer / BioNTech Covid-19 vaccines, saying “the end is in sight”.

UK revises vaccine guidelines: The UK’s chief medical officers last week released revised advice on the recommended interval period between vaccine doses for the coronavirus vaccine developed by Pfizer and BioNTech.

While British regulators had previously recommended that a second dose of the Pfizer / BioNTech vaccine be given three weeks after the first dose, British doctors this week indicated that it could be given between 3 and 12 weeks after the first dose. Likewise, the second dose of the newly authorized Oxford / AstraZeneca vaccine in the UK can be given 4 to 12 weeks after the first, as recommended.

In a letter to healthcare professionals, the chief medical officers defended their decision to extend the interval period for patients waiting to receive their second dose of the Pfizer / BioNTech vaccine, saying on Thursday the decision had been made on the basis of their assessed balance of risks and benefits. .

The British Medical Association said the move was “extremely unfair” to thousands of at-risk patients across the country.

Pfizer says it has no data to show that a single dose of its Covid-19 vaccine would provide protection against the disease after more than 21 days.
