For comparison sake the lethality of COVID-19 and smallpox were quoted as age averaged (a fair comparison for both diseases).

I've googled for discussions regarding studies of vaccine efficacy averages for individuals age >65
I found little comparative results.

i.e. Moderna, Pfizer, Janssen etc.

Establishing percentage baseline comparisons. Not between vaccines but in Delta T format between 20, 30, 40, 50, 60, 70, 80 year olds. Titer comparisons.

Guys (and Gals); this research further to the compared difference between IM and IV injection of mRNA vaccine:

"Intravenous SARS-CoV-2 mRNA Vaccine Administration Induced Grossly Visible Pathology in Heart". And, "Only IV cohort developed histopathological changes of myopericarditis".

A corrected proof Sept 16 21. This is open access, so anyone can read in entirety sans subscription:

Intravenous Injection of Coronavirus Disease 2019 (COVID-19) mRNA Vaccine Can Induce Acute Myopericarditis in Mouse Model
On edit: I made the link clickable: here-->

This research cannot be conducted on humans for obvious ethical reasons. Can anyone comment? To me, this is strong evidence that inadvertent intravenous injection of COVID-19 mRNA vaccines may induce myopericarditis in humans. A needed policy change World-wide to requiring injection aspiration?

Note: this Thread continues to be a major resource on Coronavirus / Covid; keep up the good work guys!

On the question of which provides better protection against Covid-19 infection, previous Covid-19 infection or mRNA vaccination, this preprint of a retrospective study from the VA indicates it depends upon the age of the person.

Quote:

Among seniors, Moderna and Pfizer mRNA vaccines offered stronger protection against infection, lowering the risk by an additional 66% [HR: 0.34 (95% CI, 0.14-0.78)] and 68% [HR: 0.32 (95% CI, 0.14-0.70)]; stronger protection against hospitalization, lowering the risk by an additional 61% [HR: 0.34 (95% CI, 0.14-0.78)] and 45% [HR: 0.34 (95% CI, 0.14-0.78)]; and stronger protection against deaths lowering the risk by an additional 95% [HR: 0.05 (95% CI, 0.004-0.62)] and 99% [HR: 0.01 (95% CI, 0.001-0.44)]. Among young adults (age < 65), the protections offered by vaccines were statistically equivalent to that provided by previous infection, especially in terms of absolute incidence rate.

Conclusions
Among the elderly (age 65 or older), two-dose mRNA vaccines provided stronger protection against infection, hospitalization, and death, compared to natural immunity. Among young adults (age < 65), the protections offered between natural immunity and vaccine-induced immunity were similar.

SARS-Cov-2 Infection versus Vaccine-Induced Immunity among Veterans
MedRxiv Preprint 29 Sept 2021


This study goes until August 18th, 2021 (a time frame which includes the predominance of delta).

These results may indicate why other studies are reporting conflicting results on which is better natural immunity due to a previous infection vs mRNA vaccination.

The authors conclude with this statement.
Quote:

As of September 2021, there have been 42 million reported cases according to the CDC, and four out of seven (24 million) are aged between 18 and 65. Many of them will face the decision or mandates regarding vaccination. If natural immunity is replied upon for protection against COVID-19 infection among younger adults, then we must study it carefully and follow it continuously to determine its protection relative to natural immunity plus vaccination, and vaccination alone.

Here are the conclusions from the linked mask study above
Quote:

Overall, our results demonstrate that people with mild or asymptomatic SARS-CoV-2 infections released infectious aerosols in their exhaled breath. Face masks provided significant source control suggesting that community-wide masking even with loose-fitting masks can reduce viral aerosols in indoor air by half, making a significant contribution to reducing the spread of COVID-19. Our data also suggest that the virus is evolving toward more effective dissemination through aerosols and demonstrate that infectious virus can escape from loose-fitting masks. With the dominance of newer, more contagious variants than those we studied, increased attention to improved ventilation, filtration, air sanitation, and use of high-quality tight-fitting face masks or respirators (e.g., tight-fitting ASTM F3502-21 level-2 face-coverings or respirators) for respiratory protection will be increasingly important for controlling the pandemic. This will be especially true where vaccination rates are low, vaccine is not available, and for people with poor immune responses or waning immunity. Therefore, our data support community mask mandates and tight-fitting masks or respirators for workers in healthcare but also in all workplaces where people are sharing indoor air or have frequent public contact.


You might not know you're sick with Covid-19 (asymptomatic) or you're just feeling off (mild infection) but you are still shedding virus into the air. Wearing a mask reduces the amount of virus escaping into the air that others are breathing; they're not 100% effective but they are better than doing nothing. Tighter fitting masks (i.e. KN95, etc) likely reduce the amount of potentially infected aerosols leaking around the mask.

Which source of information on why Covid-19 has declined in India should be believed, some FB post claiming use of an anti parasitic drug or the Indian government which stated in the second link strict screening for infections, proper treatment, and aggressive vaccination?

Why HCQ and Ivermectin were removed from India’s Covid-19 treatment protocol
India Today

India imposed mandatory face covering in public among other restrictions.

The vaccine lowers the chance of dying and getting extremely sick from covid.
Even with the vaccine you can still get covid, carry it and spread it.
With a 98% recovery rate I see no need to get vaccinated.
