Dear Prof. Sharma!

You pointed to a topic of great relevance. Personally I do not believe in herd immunity: COVID-19 mutant variants are about to emerge, vaccination in general in most of the countries is pretty slow and currently this virus is still spreading out:

Yours sincerely, Bulcsu Szekely

I personally feel that it will vanish, but needs some more time. herd immunity or what ever you call it, may take some more time.

I hope so! Herd immunity, by vaccination or passed infection, will be achieved at some point. Every pandemic pass, the question is when, and the cost of the period until this arrives.

Probably, COVID-19 will remain as one more respiratory viral infection, with its peculiarities, although not so severe within the people with immunity.

Thanks for useful comments.

Best regards,

Will not end the pandemic

Future of COVID-19 Pandemic

Immunity after SARS-CoV-2 infection will not eradicate COVID-19 pandemic. However, repeated COVID-19 vaccination cycles many year may help wither this pandemic to a seasonal endemic infection.

It needs time to finish

It needs time. As per Ayurveda, reduced Immunity means decreasing the essence of all seven major structural components of the body. The essence of all seven major structural components of the body decreased due to the accumulation of waste products in our body due to not following the classically prescribed daily routine or regimen, seasonal regimens, right, good or moral conducts, excessive dependency on medicine & wrong association of environmental factors. All the above factors induce the production of free oxygen radicals, activation of the hypothalamic-pituitary-adrenal axis, leading to enhanced production of cortisol and the simultaneous elevation of catecholamines. Virus infestation is now very easy to spread in our body. so removing the waste products from our body by following the classically described procedures improved immunity. A natural product like Zingiber, Curcumin will be helpful in treating corona-virus disease.If we correct all the above factors then the virus pandemic will end.

In light of all the circumstances surrounding us and the increase in the number of cases in many countries, unfortunately, I think that we may have gone back to the starting point in facing this virus in many countries of the world ...Indeed, even with the use of vaccines, we will not be able to eradicate the virus, meaning that the transmission is zero, because this virus has many natural hosts which will remain latent in them and be transmitted to humans (so, there is always a possibility to emerging new variants of this virus, and these variants may be more dangerous or maybe we are lucky and the mutations lead to weakening the virus), in addition to the presence of asymptomatic cases that serve to transmit the virus to people who are sensitive to the disease and which really makes the situation worse.

Professional answers from Manal Hadi Kanaan and M.K. Tripathi

Herd immunity against COVID-19 should be achieved by protecting people through vaccination, not by exposing them to the pathogen that causes the disease

According to the national television network news in the United States of America, as of this date, April 5, 2021, only eighteen percent of the population in this nation have received at least one innoculation of the Pfizer, Moderna, or other vaccine. Whether or not "herd immunity" could possibly end the novel COVID-19 pandemic, is, at this time, a moot point, because we have a long way to go.

I have not yet heard what the percentage is for "herd immunity"---I do not know if is it always the same. Or if this term refers to a specific percentage. Maybe it does not matter because the corona virus is transmitted faster than the vaccines can be distributed.

Another significant fact is that the loosening of restrictions in many states of the fifty USA states is coinciding with a sharply rising increase in the numbers of novel Covid-19 cases being diagnosed and unprecedented numbers of hospitalizations. Also, several new variants are causing consternation and predictions that no end is in sight because it is taking way too long for the vaccines to be distributed. By the time the eighteen percent who have already been vaccinated are ready to be vaccinated again, in six months, there will still be a great number of people who have not even gotten innoculated. In view of this current scenario in the USA, the answer to this ResearchGate discussion question is, I am sorry to say: "No, herd immunity will not end the COVID-19 pandemic."

Hello Muhammad Yusuf!

Thank you for sharing this link.

The public and health systems need to plan for the possibility that COVID-19 will persist and become a recurrent seasonal disease.

Hello Nancy Ann!

Thanks for very nice discussion on whether herd immunity will end COVID-19 pandemic or not .says that "No, herd immunity will not end the COVID-19 pandemic."

Hello Manoj Dash!

Thanks for participating in discussion about whether herd immunity will end COVID-19 pandemic or not. And explain this according to Ayurveda.

Thanks

Hello Prof. Bulcsu Szekely's!

Thank you for sharing useful information through links and participation in discussion about whether herd immunity will end COVID-19 pandemic or not .

Yes there is resurgence of SARS-CoV-2 infection with new variants continue to emerge and no of COVID-19 cases are increasing so it is not possible to achieve herd immunity.

Thanks

How much immunity after COVID-19 vaccination is enough against variants?

The JAMA article in the link below discusses this never-ending issue in the times of SARS-CoV-2 variants:

Article COVID-19 Vaccines vs Variants—Determining How Much Immunity Is Enough

Perhaps in such a situation the pandemic will end. Presumably, however, the virus will accompany us for many years. May it become harmless.

I believe that it will slow it enough to where it is not a problem anymore.

Herd immunity may never be achieved in most populated countries

At current rate of COVID-19 vaccination it may take 7 years before all population of the world above 15 years get vaccinated. However, by this time patient will need booster doses, and updated vaccines covering for all variants. Therefore, mathematically it may not be possible to get herd immunity (by vaccination of 70-100% population) of the world against COVID-19 pandemic soon for many years to come.

Although herd immunity may be achievable in countries will small populations, it would be an uphill task in countries with large populations.

In United States, millions of people are skipping second dose of COVID-19 vaccine

Please have a look on this link:

https://www.google.com/search?q=Millions+skipping+second+COVID-19+vaccine+dose&rlz=1C1GCEA_enSA905SA905&oq=Millions+skipping+second+COVID-19+vaccine+dose&aqs=chrome..69i57j33i22i29i30l9.21646j0j7&sourceid=chrome&ie=UTF-8

Having had the first dose of COVID-19 vaccine, millions of people in USA are skipping the second dose of the vaccine meaning that these people will not be able to maximize their chances of preventing recurrence of SARS-CoV-2 reinfection, hospitalization, or even death. The situation is more dire in countries that are not able to arrange the second doses in a timely manner particularly after halting Astrazeneca COVID-19 vaccine due to clotting fears.

Check these articles pls:

and

https://www.nationalgeographic.com/science/article/natural-herd-immunity-mentality-cannot-stop-coronavirus-weak-vaccine-cvd

Unlikely that herd immumity can be achieved without development of new vaccines. Mutants are not fully covered by current vaccine.

Observing what is happening in my country and in the world, it is difficult to be an optimist. Even when someone tries very hard, the likelihood of infection is still very high. Although it is not the same scale as in the past, it is already the beginning of the third decade of the 21st century.

Herd immunity is the only tool that can end an pandemic. It can be achievable either through exposure to virus/ antigen over 50 percent of population or vaccination above 70 percent of people . During this pandemic repeated exposure to virus in uts various wave mostly affects majority of the population in few years and the virus though will stay with us will be in a more weak form or strain like common cold.

Due to new mutations I don’t think so

Due to new mutations I don’t think so

Also, see the link below.

https://www.nature.com/articles/d41586-021-00728-2

I think this is the only way left now to get rid of Covid-19.

Yes,herd immunity is the best way to deal this pandemic situation

Herd immunity could, in theory, bring about the end of the COVID-19 pandemic. However the logistics of achieving this simultaneously worldwide before new variants emerge that can evade the current vaccine make the possibility of developing herd immunity unlikely.
