Bad (wrong) advice from a cardiologist goes viral. Dr Peter McCullough from Baylor college Texas says:

“People under 50 who fundamentally have no health risks, there’s no scientific rationale for them to ever become vaccinated”

⚠️This is wrong advice.

factcheck.afp.com/us-cardiologis…
The reasons he is wrong are:

1. Comorbidities are not the only reason people get sick. Their role in causing severe disease is overestimated. One could be otherwise healthy & still die from it.

2. ~15% of deaths (India data) are below age 45. They deserve protection too.

2/4
3. By reducing the risk of infection, vaccines have a role in diminishing the R-0. Vaccinated people are less likely to give the virus to others. Evidence is emerging on this.

(It is true that a few could still get asymptomatic or mild infections after vaccination)

3/4
4. The only age group that has negligible risk of death in the event of COVID-19 is children of 1-14 years. Their death risk if they get virus, is 1:50,000.

It will be statistically almost impossible to prove that vaccines can reduce that incredibly small rate any further.

4/4

AstraZeneca Vaccine and clots: this important paper from Germany proves that VITT is not the result of cross-reactivity between anti-spike antibodies and platelet factor 4 (PF4).

See thread and links below 👇

researchsquare.com/article/rs-404…
VITT is vaccine-induced thrombotic thrombocytopenia, an extremely rare and serious complication with low platelet count & unusual clot formation.

This is being extensively discussed in the context of AstraZeneca’s COVID vaccine.

This thread explains the research above.

1/n
The researchers’ findings also suggest that PF4 antibodies are likely an “innocent bystander” in many patients. In other words, their presence alone does not predict disease.

In fact, 9 of 10 COVID-19 patients who had thrombosis did not have PF4 antibodies.

EMA press conference 7 April on vaccine safety

1. Very rare 1:100,000 to 1:600,000 risk of clots with AZ vaccine

2. J& J, a similar vaccine, had a similar case during clinical trials, & 3 cases of unusual clots & low platelets later

1/6
via @YouTube
3. When reported case numbers are so very small, it is difficult to comment on the exact amount of risk involved, but the risk of COVID-19 far outweighs any adverse outcomes from vaccines.

4. AstraZeneca has been asked for related data on past trials & ongoing trials

2/6
5. AZ has been asked to do lab studies about how its vaccine can affect clotting

6. University of Utrecht and Erasmus University will be studying the topic of clots, reports expected in ~2 months

7. The pattern does not support link with hormones (OC pill, pregnancy etc)

Video by John Campbell, a nurse lecturer from 🇬🇧 UK about the possibility of inadvertent injection of vaccine into a blood vessel as a potential cause of fatal blood clots following vaccination.

My recent tweet on this is attached. I have also explained it in my diagram.

1/9
If you blindly inject in the arm a 100,000 times, there is a rare, very rare chance the tip of your needle is sitting inside a tiny blood vessel. That’s basic 7th grade high school probability, not rocket science. Astra vaccine contains 5000 million live viruses in each dose.
2/9
These are live chimp adenoviruses who are genetically “sterilised” that is, they can’t replicate.

But they are meant to be deposited in the deltoid muscle - from where our dendritic cells are expected to pick up the spike protein that is generated as a result.

Taking an exam in a classroom with social distancing & protocols in place is a relatively safe activity. The risk is a lot higher in regular classes where children sit in crowded rooms for several hrs & talk. Discussion on @IndiaAheadNews @Smita_Sharma feasibility of CBSE exams.
The risk for transmission is greater when people sit together and talk for a long time in closed spaces without masks. Shorter time spent, less talking fewer people and more ventilation will reduce risk. ImageImage
Children have extremely low risk of dying from COVID-19, as I discussed yesterday. See the graphs.

Overall death risk is 1 in 1 million (much lower than other causes of death at that age), and 1:50,000 if they got COVID-19. @IndiaAheadNews @Smita_Sharma @PIB_India @IMAIndiaOrg

Hungary 🇭🇺 has the highest vaccination coverage in the EU, yet has the highest death rate. Shows that the mortality is related primarily to the large number of vulnerable people in any country.

abouthungary.hu/covid-vaccine/
The protective effect of vaccination will likely be apparent when the next wave hits. It takes time to not only cover the majority of the population, but also for protective immunity to kick in. Image
Useful timeline of pandemic preparedness and vaccine coverage in Hungary. Overall death dates will not drop as soon as vaccination starts. This takes rime. But when we compare death rates among vaccinated and non-vaccinated, there will be a difference. abouthungary.hu/covid-vaccine/

Could faulty injection technique explain the rare clot disorder with COVID-19 vaccine?

If the tip of the needle doesn’t reach deep enough in the muscle or if it hits a blood vessel, the vaccine can be directly injected into the bloodstream: an extremely rare possibility.

1/6 Image
This can happen when the skin is pinched up by an inadequately trained health worker. (IM injections are meant to be given without pinching up skin, so that the needle tip reaches the muscle)

When skin is pinched up, the needle tip reaches only the subcutaneous tissue.

2/6
When that happens, not only is the vaccine not absorbed properly, but rarely it can hit one of the blood vessels that travel through this layer (this is marked in yellow in my diagram, it is located between skin and muscle). This layer contains a network of blood vessels.
