Know How the Covid-19 Vaccines Works

When your body fights off a virus, it makes antibodies that act like the troops, they learn what the enemy looks like so they can fight it again successfully in the future. Vaccines help us do that training our immune soldiers to be ready in the war against covid.

The goal of the vaccine is to induce the immune response that's a consequence of natural infection without making people pay the price of natural infection. The Vaccine does the work this week the first evidence the one from Pfizer and its partner biontech is working. It's one of three different approaching methods scientists are taking in the u.s. Dr. Paul offit says they all have the same goal, show the immune system part of the coronavirus. So before you get sick, your body can make the protective antibodies.

He said that We know the protein of the virus that were interested in it's that Spike protein the protein that sits on the surface of the virus that allows the virus to attach the cells. If you can prevent the virus from attaching to cells then you can prevent the virus from infecting cells and affecting you.

Vaccines from moderna Pfizer and others do this by delivering a piece of genetic material called messenger RNA. It tells ourselves to make that Spike protein to which we then develop antibodies. Other vaccines from AstraZeneca and Johnson & Johnson also employ a new approach using a different harmless virus to deliver the gene telling ourselves to make that protein again, 

Again you make the coronavirus Spike protein, then you make antibodies to the coronavirus by croaking. That's the way those systems work. 

The third is a familiar technology being used by Sanofi, Glaxo Smith Kline and Novovak's and this approach the spike protein itself is delivered, skipping steps requiring ourselves to make it,

It's the way that we make the human papilloma virus vaccine. It's the way we make the hepatitis B vaccine. That's the way we make one of the flu vaccines off. It says each approach may have benefits and drawbacks for instance one might work better for older or high-risk people, but we don't know yet and we won't know until the third phase of Trials is complete for all of them. 

The proof is in the pudding the pudding is these phase three trials. Which among these vaccines will be the best last vaccine will find out.
