The approach towards Covid-19 herd immunity has become a trending discussion to fight against the virus. The question is, can we consider it as a smart strategy to combat Covid-19? Some European countries initially planned to suppress the virus gradually instead of eradicating it entirely. The idea was to build herd immunity by exposing people, giving them the illness, and making them immune. Read on to know more about Covid-19 herd immunity and how useful it is in the Covid-19 battle.
Is Covid-19 Herd Community Effective? Can We Do That?
Let us tell you a bit about what herd immunity is before you make any conclusions. Herd immunity is the indirect protection from an infectious disease. It happens when the entire population is immune to that disease either through vaccination or immunity developed through the previous infection. The vaccination and immunization from the previous infection will act as a protective shield. To some extent, they will also help safeguard unvaccinated or people who aren’t immune to the particular disease by controlling the spread of the infection. Once herd immunity has been established, it will halt the disease spread and the disease can eventually be eliminated.
The next question: how many people need to be immune for herd immunity to take effect?
This depends on the contagiousness of the disease. For mumps, you need 92% of the population to be immune, for measles it comes to 93 – 95 % to stop the disease spread entirely.
Where Do We Stand Applying Herd Immunity For Covid-19?
The best way to achieve herd immunity is through a vaccine. However, as of now, we do not have that luxury. That’s because a large population needs to be immune to reach herd immunity. According to experts, Covid-19 has a lower infection rate than diseases like measles, and herd immunity should be achieved when around 60% of the population becomes immune to Covid-19. Having said that, natural herd immunity achieved through infection is challenging to induce in the Covid-19 pandemic. That’s because of the high rate of illness and death of the virus, due to which medical systems in countries have gotten overwhelmed. The risk is simply not worth the reward in this case.
Immunizing a Covid-19 herd community will help make a large population resistant to the virus. So as of now, the best way forward is social distancing to avoid infection till we find a vaccine to fight against Covid-19.
FAQs On Covid-19 Herd Immunity
Why Do Some People Get Fever After Getting Covid-19 Vaccine?
The vaccine has an antigen that triggers the immune system. As a result, the immune cells in the body tend to increase the blood flow thereby increasing the blood circulation in the body. All of this increases the body temperature which comes up as fever in the body.
Is It Necessary To Take Two Doses Of Covid-19 Vaccine?
Yes, it’s important to take two doses of the Covid-19 vaccine in order to completely avail of the benefits of the vaccine. Do keep in mind that both the doses you take must be of the same vaccine type.
Which Is The Largest Covid-19 Vaccination Drive In The World?
The National Covid-19 Vaccination Drive in India can be considered the largest in the world.
Who Are At A Higher Risk Of Developing Serious Illness From Covid-19?
Older people are at a higher risk of developing serious illness from Covid-19. Apart from them, people suffering from diabetes, cardiovascular problems, chronic respiratory disease, and cancer also are at a high risk of getting seriously ill from Covid-19.
