Minsalud also announced that stage II of the National Vaccination Plan begins. From the next week, people between 75 and 79 years old would begin to be vaccinated.
In the Prevention and Action program, the Minister of Health, Fernando Ruiz made two announcements about the National Vaccination Plan:
A single dose of the Pfizer vaccine will be given to people between the ages of 18 and 60 who have had the coronavirus
The Presence Vaccine Advisory Committee recommended that a single dose of the Pfizer / BioNTech vaccine be given to people between the ages of 18 and 60 who have had coronavirus. Why? Studies published in recent days say that the protection achieved with a single dose is greater than the immunity generated by having had the disease and strengthens the immunity of people who have already had coronavirus. The Presidency’s Vaccine Advisory Committee made the recommendation for this specific vaccine (for those who have not had coronavirus, the dose of two applications will be applied).
Ruiz refers to six recent studies suggesting that people who have already contracted COVID-19 may not need to receive a second dose of vaccine. According to the New York Times, countries like the United States have not changed their recommendation for a second dose, but studies looking at the immune response show that while a first injection is given to people who have recovered from COVID- 19 a big boost, the second shot makes little difference.
For someone who has had COVID-19, the first injection is like a person without COVID-19 receiving a booster – it even has the side effects of someone receiving a second dose of vaccine.
Another of the new studies, a preprint from the University of Maryland, showed that 41 healthcare workers who recovered from COVID-19 had more antibodies after their first injection than 69 of their peers who had not contracted the virus after the second.
And another preprint from the Fred Hutchinson Cancer Research Center in Seattle found that the blood of people who recovered from COVID-19 was not as good at neutralizing the original virus or the variant that originated in South Africa as the blood of people who recovered. they had recovered and were vaccinated. Three other studies had similar findings.
With respect to the Chinese Sinovac vaccine, which arrived in Colombia two weeks ago, the general efficacy is 51.1% and the second dose “gives a protective effect equal to or greater than the protective effect that occurs with the application for 28 days. Applying the second dose 56 days after applying the first dose protects and therefore the recommendation is that the second dose be extended to Sinovac 56 days after the first application ”, explained Ruiz.
Vaccination begins for those over 75 and under 80 years of age
Minsalud also announced that stage II of the National Vaccination Program begins tomorrow, that is to say that starting next week, people between 75 and 79 years of age will begin to be vaccinated, so the IPS will have to start scheduling appointments tomorrow. . On Tuesday it is calculated that the vaccination of the population over 80 years of age will end, and according to Minister Ruiz, there is sufficient vaccine availability to vaccinate these populations.
“For the epidemiological moment that we live, it is very important to continue with the vaccination. Covid-19 has been declining substantially and we must seek to prevent the possibility of a third outbreak at the national level ”.
