2. Global impact (expressed as correlation) of COVID-19 Vaccination
In the last 14 days (14-27 September 2021)
• Analysis of data available online for COVID-19 cases & deaths (Source:
https://www.worldometers.info/coronavirus/weekly-trends/#weekly_table), and percent
vaccination (Source: https://en.wikipedia.org/wiki/Deployment_of_COVID-19_vaccines) for
countries having more than 10 million people indicated a highly
significant positive correlation i.e., more vaccination was associated
with more disease & more deaths.
• On analyzing matching data available for all 193 countries also
indicated a very strong positive correlation with the number of
COVID-19 cases.
• There is no positive indication that COVID-19 vaccines are protecting
the vaccinated populations of different countries in the world.

4. Impact (expressed as correlation) of COVID-19 Vaccination in India
Cases and deaths due to COVID-19 in the last 14 days (14-27 September 2021)
Analysis of data available online for COVID-19 cases & deaths, & % vaccination (Source:
Source: http://data.covid19india.org) for 28 states and 8 Union territories of India using a
variable number of dosages of three different vaccines of COVID-19 revealed that:
• 1. More vaccination was linked with more deaths.
• 2. The first dose of vaccine was associated with a significantly higher number of Adverse
Events Following Immunization (AEFI), after 2nd dose, adverse events were less.
• 3. Adverse events were more often associated with CoviShield and less often with Covaxin
and Sputnik V.
• 4. COVID cases and deaths were more in regions using more CoviShield (positive
correlation) than those using Covaxin and Sputnik V (negative correlation).

6. What to Do?
• 1. The immediate stoppage of the use of leaky, largely
ineffective, and reactive COVID-19 Vaccines.
• 2. Promoting the development & use of whole virus vaccines
either inactivated (like Sinopharm and Covaxin) or attenuated
live (yet to be developed).
• 3. Promoting the judicious use of COVID-19 vaccines
(https://azad-azadindia.blogspot.com/2021/03/how-judicious-is-
covid-19-vaccination.html).
7. Herd-Immunity
• A false notion for airborne and aerosol infections
• Not work well with the population moving and mixing with
different groups frequently (Human population).
• After all, we are not herds of cattle or flocks of sheep to get
advantages of herd immunity.
• It is a spoof floated by pharmacopoliticians to earn the money
and bluff the people through creating panic and fear.
