Giving the two doses of the Pfizer vaccine 3-4 weeks apart is in line with the manufacturer\u2019s guidance.<\/p>\n<p>2. This is what most other countries using the Pfizer vaccine are doing.<\/p>\n<p>3. Evidence from randomised controlled trials and subsequent evidence from real-world data provides strong evidence that two doses of Pfizer vaccine given 3-4 weeks apart provide excellent protection against severe disease and death<\/p>\n<p>4. Data from Public Health England shows that two doses of vaccine provide much better protection against the delta variant than one dose. Hence, giving second doses after 3-4 weeks instead of after 8-12 weeks could help reduce the current ratee of infection in the UK<\/p>\n<p>5. Many people are keen to get their second dose of Pfizer vaccine quickly because of concerns about other family members or to help them travel.<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Early on during the pandemic, the UK government took the decision to give second doses of the Pfizer Covid-19 vaccine after 12 weeks rather than the recommended 3-4 weeks.
