Vaccines, it is better to give the full dose (first dose and second dose after 3 or 4 weeks) and therefore protect people more effectively, or try to vaccinate as many people as possible with the first dose, thus settling for protection. minor, and then inoculate the second only after 12 weeks? Demand is bouncing between the UK and the US, where the epidemic is unfolding, hospitals are at their last resort, the death toll is very high.
The United Kingdom, immediately after the approval of the AstraZeneca vaccine that joins that of Pfizer-BioNTech, has decided to change strategy: we are in an emergency, the first dose to as many people as possible, the second only in four months . The UK Joint Committee on Vaccination and Immunization (JCVI) has recommended that “a first dose of the vaccine be offered to as many people as possible sequentially as an initial priority.” The second dose of the ‘Pfizer / BioNTech vaccine can be administered between 3 and 12 weeks after the first dose and the second dose of AstraZeneca (Oxford) vaccine can be administered between 4 and 12 weeks after the first dose’.
The UK government website says: “All four UK Medical Directors agree with the JCVI that, at this stage of the pandemic, prioritize the first doses of vaccine for as many people as possible in The priority list will protect the most number of people at risk as soon as possible and will have the greatest impact in reducing mortality, serious illness and hospitalization and protecting the NHS and equivalent health services. Operationally, this will mean that the second doses of both vaccines will be given towards the end of the recommended 12-week vaccine dosing schedule. This will maximize the number of people who will receive the vaccine and therefore receive protection in the next 12 weeks ».
In the United States, where the vaccination campaign is lagging behind, super expert Anthony Fauci has opened up to such a change in strategy, but the debate is ongoing.
