There is not any want to vaccinate individuals who had documented COVID-19 an infection, well being experts mentioned.

A gaggle of public well being experts, together with medical doctors from AIIMS and members from the nationwide taskforce on COVID-19, have mentioned that mass, indiscriminate and incomplete vaccination can set off emergence of mutant strains and beneficial that there isn’t a want to inoculate those that had documented coronavirus an infection.

In their newest report, the experts from Indian Public Health Association (IPHA), Indian Association of Preventive and Social Medicine (IAPSM) and Indian Association of Epidemiologists (IAE) mentioned vaccinating the susceptible and people in danger, as an alternative of mass population-wide inoculation together with youngsters, needs to be the goal at current.

“The current scenario of the pandemic in the nation calls for that we needs to be guided by the logistics and epidemiological knowledge to prioritise vaccination moderately than opening vaccination for all age teams at this stage.

“Opening all fronts simultaneously will drain human and other resources and would be spreading it too thin to make an impact at the population level,” the experts mentioned in the report which has been submitted to Prime Minister Narendra Modi.

Highlighting that vaccination of younger adults and kids is just not supported by proof and wouldn’t be value efficient, they mentioned unplanned inoculation can promote mutant strains.

“Mass, indiscriminate, and incomplete vaccination can also trigger emergence of mutant strains. Given the rapid transmission of infection in various parts of the country, it is unlikely that mass vaccination of all adults will catch up with the pace of natural infection among our young population,” they mentioned in the report.

There is not any want to vaccinate individuals who had documented COVID-19 an infection. These individuals could also be vaccinated after producing proof that vaccine is useful after pure an infection, the suggestions said.

Evidence-based flexibility in vaccine schedules may have to be thought-about for areas or populations experiencing surge on account for particular variants; for instance, a lowered interval for the second dose of Covishiled for areas with surge due to the delta variant.


“Vaccine is a strong and powerful weapon against the novel coronavirus. And like all strong weapons it should neither be withheld nor used indiscriminately; but should be employed strategically to derive maximum benefit in a cost-effective way,” they mentioned.

While it makes excellent sense to vaccinate all adults, the fact is that the nation is in the midst of an ongoing pandemic with restricted availability of vaccines, the report mentioned.

In this state of affairs the main focus needs to be to scale back deaths, majority of that are amongst older age teams and people with co-morbidities or weight problems.

Vaccinating younger adults, given the current constraints, is not going to be cost-effective, they said.


The report advised implementing repeated native degree serosurveys in actual time on the finish of the second wave to map the vulnerability at district degree to information vaccination technique and long run comply with up of the cohort of recovered COVID-19 sufferers to doc re-infection, severity and final result to present proof base on period of immunity after pure an infection.

Ongoing analysis on vaccine effectiveness underneath discipline situations by following cohorts of vaccinated and unvaccinated in totally different age strata needs to be prioritised.

Stating the present wave is essentially attributable to a number of variants, the experts identified that India has finished genome sequencing of lower than 1 per cent of its constructive samples and in addition lags behind different excessive incidence international locations in one other essential measure, sequence per 1,000 instances.

Achieving a goal of genomic sequencing of 5 per cent constructive samples appears difficult for the time being, however all efforts needs to be made to attain no less than 3 per cent mark, they beneficial whereas appreciating organising of the Indian SARS-CoV-2 Genomics Consortium (INSACOG) of 10 nationwide laboratories well timed and addition of 17 extra laboratories.

The molecular epidemiology investigations want to be accelerated with INSACOG scientists, discipline epidemiologists and medical specialists working in synergy to delineate the epidemiological options of the variants with particular reference to transmissibility and fatality.


Genetic sequences want to be tracked to delineate virus transmission each throughout the neighborhood and in well being care settings.

It can detect outbreaks that will in any other case be missed by conventional strategies, the experts identified.

They additionally beneficial that syndromic administration strategy needs to be rolled out in a deliberate method after sensitisation of healthcare workers, together with the optimum utilisation of laboratory testing.

There is an acute scarcity of testing amenities for SARS-CoV-2 in rural and peri-urban areas.


The sensitivity of RAT is kind of low; there are probabilities that some actually constructive instances would stay unidentified and thus proceed to unfold the illness.

“Timely testing of each and every symptomatic patient is not possible and will put a huge burden on the health system and will delay the isolation and treatment. The optimal solution in such a situation is to adopt a syndromic management approach. It should put focus on making diagnosis based on clinical symptoms and epidemiologically linked suspects,” they mentioned.

They additional beneficial that the vaccination standing of all people examined for COVID-19 have to be entered into the pattern referral type in the RTPCR app each for people examined by RTPCR and RAT.


The collected data have to be analysed periodically to know the standing of vaccinated people with regards to COVID-19 and its severity together with mortality.

As means ahead, the experts mentioned that district degree sero surveillance could also be deliberate with the methodology of EPI cluster sampling.

” If the seroprevalence at district degree, is greater than 70 per cent (on account of a mix of pure an infection and vaccination,) there shouldn’t be any lockdown and return to normalcy needs to be tried.


“This will also help in prioritizing the districts for vaccination i.e. districts with lower seroprevalence should be given priority for vaccination. A fine balance is needed to be maintained between life and livelihood.”

The experts additionally mentioned that if very giant variety of people are vaccinated at a quick tempo with restricted sources for monitoring of adversarial occasions following immunization (AEFI), some adversarial occasions and deaths will likely be missed.

Also, whereas a few of these AEFI could also be coincidental, it could find yourself contributing to vaccine hesitancy.
