Bivalent vaccine: information of interest

The bivalent vaccination against covid-19 is so named because it contains two protective components that enable a better immune response of the body to the infection.

The first protects you from the original virus and others, from lineages omicron variant that prevails in the world, according to experts.

This vaccine could be a turning point in the race against COVID-19, because the composition of the vaccine offers wider protection, pointed out Dr. Yamile Sandoval, medical manager of Asofarma’s vaccine department.

“This extends virus protection to protect from the ancestral strain, as well as against possible future variants, this is based on analysis of the composition of variants and sub-variants,” he explained.

Real-world evidence has shown that the bivalent vaccine can prevent disease severe infection, hospitalization, and even death have been shown to be more effective against severe omicron infection than booster vaccination with monovalent vaccines or vaccines containing only the ancestral strain, according to a press release.

He assured: “The goal to be pursued by applying the booster dose bivalent vaccine is to potentially expand the body’s immune response and improve the durability of neutralizing (protective) antibodies so that the body can better respond to variants as they arise, which is critical for endemic disease.”

So, due to the variability of the virus, there is a possibility that vaccine manufacturers they must update the vaccine formulation at least once a year, as is the case with current flu vaccines.

In the case of Moderna, its technology platform based on mRNA (messenger RNA) enables a significant reduction in production time without compromising the quality and safety of the vaccine, which allows it to develop rapidly bivalent vaccines apply the boost that the population needs, taking into account the variants of the virus circulating at a given time.

Clinical evidence has shown that bivalent vaccines As booster doses, they are the most effective and efficient tool to protect the population, save lives and avoid new isolation measures, since they strengthen the immune system of people by maintaining elevated antibodies that protect against COVID-19 and create herd or collective immunity

Everyone should know the benefits of getting vaccinated against covid-19, as well as that different governments include bivalent vaccines in their vaccination schedules as well as countries like Colombia, Argentina, Chile and Peru who procured doses for the population of 6 months of age.
