You are devising a vaccination program for a strain of influenza with an estimated R0 of 2.5. What proportion of a susceptible population do you need to vaccinate to impart herd immunity and prevent an epidemic

It would seek to vaccinate those young people who have complete and strong immune systems, that is, without pathologies that trigger immunosuppression or immunodeficiency and without underlying systemic pathologies.

In this way it is ensured that part of the population makes antibodies to this virus.

Not only with this group of people an epidemic would be avoided, but it will also seek to vaccinate those people whose health is not affected by being vaccinated and are asymptomatic carriers at risk of spreading to the vulnerable population, an example of this would be to vaccination of children who would be the most frequent to become ill, with fewer symptoms and greater risk of spreading the virus in vulnerable populations such as the elderly or immunosuppressed adults.

Explanation:

In all, compared to other viruses, this R0 value is considered relatively low compared to the measles or chickenpox virus.

The r0 is a value that is assigned to microorganisms that are at risk of spread between humans, thus triggering possible pandemics, epidemics, etc.

The higher the R0 value, the easier the microorganism spreads and the less its infection can be prevented or the more difficult it will be to control by the health system.

The r0 in simple words is the number of people to whom a person infected or infected would transmit the disease.

On the other hand, the influenza virus is a virus that is mutating and acquiring different characteristics, with which there are different strains from year to year that is why the vaccination plan has to be renewed.
