In recent months much has been said about the community immunity or herd to create antibodies that help fight this coronavirus that has stopped the world.
Butwhat is community or herd immunity and why many people believe that it could be the solution to end this pandemic even with the SARS-COV2 vaccine?
Dr. Wesley Long, pathologist and researcher at Houston Methodist Hospital, explains that, “Community immunity occurs when there is initially an infectious disease and a population of individuals who do not have immunity to this disease, which is why they can be easily infected , but at the same time they develop antibodies to fight this disease until the contagion is not so easy and is decreasing. “
He added that, “the concept of herd immunity is that people get infected and become immune and that reduces the spread of infection because even if you have an infected person and the people around them are immune, they cannot spread it and therefore slows it down the transmission if it is not from person to person. “
Given the arrival of the new coronavirus, some governments and people in the world inferred that exposure to this virus would be a good idea for them to contract the disease and thus create antibodies to be able to fight it and thus be immune to a regrowth, however, to Many the result was not what was expected and the outcomes are being fatal, as we see in the current mortality rates around the world.

“Trying to achieve herd immunity through a natural infection, for example, people who naturally contract the coronavirus, is very dangerous because it means that a large number of people get sick, health services are overwhelmed, many people suffer effects from long term and people around the world will die trying to achieve herd immunity through natural infection, ”explained the Houston Methodist Hospital pathologist.
“I don’t see any advantage in trying to achieve herd immunity through natural infection because we are already seeing evidence that some people can still get infected again 5 or 6 months later. I believe that the best way to try to achieve herd immunity is through vaccination, not through natural infection, as currently licensed vaccines appear to provide a stronger immune response without the dangers of infection, ”added Dr. Long. .

Regarding reports of coronavirus mutations and the possibility of a vaccine, Dr. Long explained: “So far, we have not found any mutation that could interfere with the usefulness of the vaccines developed. Obviously, we will have to monitor how the virus evolves, but in the meantime, we must vaccinate immediately. We may have to formulate a new vaccine every year to better adapt to the virus that is circulating in the future. This is not yet known, but it can be done, ”concluded Dr. Wesley Long.
