Health has changed its criteria in the recommendations on the booster doses of the COVID-19 vaccine in those people who have just had the disease. The complete schedule of vaccines consists of two doses, in the case of the messenger RNA type such as Pfizer-BioNTech and Moderna, and traditional ones such as AstraZeneca, and one in the case of Janssen. However, as the pandemic progresses and new variants emerge, an extra injection has been recommended to continue maintaining that protection against SARS-CoV-2, which must be remembered that it does not prevent contagion, but it does protect against serious illness.
This booster dose – called by many the third dose as it corresponds to this order in mRNA doses – has been recommended in Spain for the population over 18 years of age, provided that at least six months have passed after the last dose of the primary vaccination or guideline. complete. In addition, a period had been established for its administration in the cases of patients who had just passed the disease, which at first indicated that it could be applied only four weeks after diagnosis.
Now, the Spanish Public Health Commission has announced that, although this booster dose can be received at four weeks as previously stated, it is recommended that it be administered at least five months after a positive PCR test. or an antigen test.
Health has recommended that unvaccinated children who have passed the infection only receive one of the doses and at least 8 weeks after diagnosis
“Current evidence shows that the fact of having a SARS-CoV-2 infection after having the complete primary vaccination schedule causes a more powerful and broader immune response to be developed in terms of neutralizing other variants of the virus, compared to the immune response seen in people who only had infection, or who received only two doses. In addition, omicron infections increase the response of memory cells to viral antigens other than protein S compared with post-vaccination infections caused by the delta variant, implying a broadening of immunity. Public Health Commission.
Changes in the vaccination of children who have passed COVID-19
In addition, in this latest update of the Vaccination Strategy against COVID-19, it has also been reported when children between 5 and 11 years of age can be vaccinated after infection with the coronavirus. There are two assumptions, the first is when the infection occurred before the administration of either of the two doses of the vaccine, in which case a single dose of the vaccine should be injected at least eight weeks after the positive diagnosis.
The second case is when the infection occurs after the child has already received one of the doses of the vaccine, and in this situation the second will be administered from the eighth week after testing positive for SARS-CoV-2, and always maintaining an additional eight weeks apart from the first dose.
