India COVID19 vaccination, what we did and what we should have done?

Now that we have seen this post👇, do not how LOW is our coverage(%) of 2nd dose(fully vaccinated) among elderly / >45y
2/n
Therefore with these levels of LOW coverage, we cannot expect any dent in the hospitalisations and deaths

We missed a window of opportunity during Feb/Mar
3/n
Had we at least achieved 89-90% of 1st dose coverage along >45, we could have expected significant impact on hospitalisations and deaths. We could have done this through campaign mode vaccination using our public health vaccination system through apriori microplanning.
4/n

This includes
1. Ensuring around 40 crore doses are available for >45y
2. a priori training, estimating dose requirement and preparing strategy, PHC by PHC
3. Providing those vaccines to state / district / PHC as per the microplan
4. PHCs implementing their microplan
5/n

If vaccine stocks was an issue, we could have used sectoral approach. This could have been done at least in cities and districts where cases and deaths were high or rapidly increasing or predicted to increase. Then in other cities and districts.
n/n

We did not have sufficient vaccines and spread out thin and did not miss out on Propaganda without realising how flawed our CoWin dependent strategy was.

Many experts had called it out. I did so on 2 March (including writing to Health Min, GoI)

#WrongCOVIDVaccinationStrategy

All India had to do in Feb/Mar 2021 was complete both doses for >45 y in campaign mode (at least in elderly, at least in high burden districts)
That required planning in advance, procuring 40 crore doses and distributing to the states
2/5
#WrongCOVIDVaccinationStrategy

The states distribute it to districts and PHCs based on the estimated requirement in microplans.
Vaccination should have been done using our pubic health vacc system that is decentralised upto the Anganwadi through bottom up micro-planning

#WrongCOVIDVaccinationStrategy
We missed this window of opportunity and here were are.

We are spreading out thin without adequate coverage in vulnerable. This will not dent cases and hospitalisation. the limited coverage also appears inequitable

One tip

If a covid patient at home has a dip in oxygen levels (<94%) despite a 6 min walk test that means they need to get admitted in a covid bed with at least oxygen.

If a bed is available, public or private, get them admitted without DELAY

No If No But
.....
After reaching hospital, hospital says only bed with O2 available, no ventilator

Mistake that people do this travel around looking for bed with ventilator (just in case)

My suggestion would be to get admitted if a bed with O2 is available esp in these times.
...
At home, monitor O2 every two-four hours using a pulse oximeter. DO NOT take this lightly.

#India #WrongCOVIDVaccinationStrategy

We as Indian public, media as well as the Govt lose the plot when we start talking about absolute numbers and vaccinating entire population, at least for now

1/n
For immediate reduction in hospitalisation and deaths (within 4-6 wks), we should ensure a rapid and wide coverage of COVID-19 vaccines in >45y population.

So
Ask data for coverage among these vulnerable pop.
Ask, is the current CoWin dependent strategy appropriate?

2/n
>45 are roughly one-fifth of the population. We should cover these using our public health vacc system thru decentralised approach (no need for CoWin). If vacc supply is the issue use sectoral approach. By spreading out thin we are not denting admissions and deaths.

Thread 🧵
India should urgently change its COVID-19 vaccination strategy - why and how?
@MoHFW_INDIA @NITIAayog

(1/25)
Change in strategy is not as simple as making vaccination open to all (vacc criteria).
Still after 35 days of phase II, the numbers suggest that the coverage among elderly is abysmal and this needs immediate correction

(2/25)
Opening the vaccination to all will spread thin the already available doses. And it will also be an implementation nightmare.
This sounds fine at individual level but impractical and not correct at population level.
Again context specific exceptions could be made

@BWDDPH @BWDDPG @janisfrayer @pash
I watched the video with interest. I have been following the COVID-19 numbers and here is my take esp on the deaths.

To infer the extent of COVID-19 mortality in India using ‘reported’ COVID-19 deaths is not correct. Let me explain.
(1/n)
@BWDDPH @janisfrayer @pash In a scenario of very high seroprevalence (20%), very low covid case detection rate (3.6%), very poor coverage and quality of routine death surveillance (18% coverage), and low % of deaths in hospitals (34%), for me the reported covid deaths are waay lower
(2/n)
@BWDDPH @janisfrayer @pash Also, There is limited excess deaths data in public domain, there are no post mortem COVID-19 studies (testing all deaths post-mortem in a study area / period for COVID-19), we are not reconciling data from routine death surveillance (however good or bad it is)

I will share death registration and medical certification of cause of death coverage in India-state by state. One tweet per day.
In the absence of reliable cause of death data, how can we effectively plan to reduce cause specific deaths? (1/n) #CRS #MCCD #RoutineDeathSurveillance
In India,
86% of estimated deaths are registered (CRS report 2018)
21.1% of registered deaths undergo cause of death certification (MCCD report 2018)

Therefore
18.1% (86%*21.1%) of all estimated deaths undergo registration along with cause of death certification
(2/n)
In Andhra Pradesh,
100% of estimated deaths are registered (CRS report 2018)
14.9% registered deaths undergo cause of death certification (MCCD report 2018)

Therefore
14.9% (100%*14.9%) of estimated deaths undergo registration along with cause of death certification
