Health proposes a third dose for people over 40 with priority for those who were vaccinated with AstraZeneca
The Vaccine Conference, the experts who advise the Ministry of Health in the design of the Vaccination Strategy, joins the European trend and calls for a third dose to be given to everyone over 40 years of age, giving special priority to those vaccinated with AstraZeneca. This has been confirmed by Vozpópuli, who has accessed the document that the autonomous communities will discuss this Wednesday at the Interterritorial Council.
The advisers from the Ministry of Health propose "covering people aged 40-59 years with the memory dose, prioritizing those vaccinated with AstraZeneca's homologous regimen under 60 years of age (many of them already vaccinated within the groups of sanitary and socio-sanitary and other essential) from 3 months of the last dose".
In other words, people who received two doses of AstraZeneca in the 40-59 age group, mainly health personnel, police officers, civil guards, soldiers and teachers, will receive a third dose of Pfizer or Moderna if the communities autonomous communities are satisfied at the meeting on Wednesday.
The Report on Vaccines justifies this decision, alleging that "the current epidemiological situation with an increase in the incidence rate of up to 248 per 100,000 inhabitants, and also the increase in hospitalizations and deaths from covid-19 in the sixth wave of the pandemic, In addition to the appearance and spread of new variants of concern (VOC) such as Ómicron, it makes it necessary to consider the administration of booster doses of the vaccine against covid-19 to larger population groups with the aim of increasing protection".
To these circumstances, the experts add that various national and international effectiveness studies indicate a drop in protection also in people between 18 and 60 years of age, especially against infection, and also for mRNA vaccines . They also cite the document published by the European Center for Disease Prevention and Control (ECDC) where they recommend that the vaccine advisory committees of member countries consider administering a booster dose in people over 40 years of age, and that they also consider vaccination as a souvenir for those over 18 years of age.

In turn, they indicate that the application in various European countries of a covid passport that takes memory doses into account makes it necessary to make a decision in this regard. In Spain, the group between 40 and 59 years old is made up of 15 million people.
Loss of efficacy
The Vaccine Report cites in its document the study on the effectiveness of vaccination carried out in Spain. In people aged 50 to 59 (population group that received different types of vaccines), the Vaxzevria (AstraZeneca) vaccine is less effective than Comirnaty (Pfizer) and Spikevax (Moderna), especially against symptomatic infection. (68% vs. 78% and 89%, respectively).
In another study carried out in Navarra studying secondary cases of coronavirus infection in close contacts, "less effectiveness (54%) was observed against infection of the AstraZeneca vaccine compared to the Pfizer or Moderna guidelines, reaching 86% the AstraZeneca-Pfizer regimen; 69% for Pfizer's double regimen; and 82% for Moderna's."
Regarding vaccination of children under 12 years of age, experts consider that priority should be given to those who are most vulnerable and to the 10-11 age group. They also insist that in the current epidemiological context, "vaccination is a priority in people 12 years of age and older who have not yet completed the primary vaccination and the administration of booster doses in the older population."
