HELLO THERE! SRY I GOT DELAYED TO POST THE OTHER BLOG DUE TO SOME CIRCUMSTANCES. IN THIS BLOG YOU MAY LEARN MANY THINGS WHICH EVERYONE SHOULD LEARN AND KNOW! THEREFORE READ CAREFULLY CAUSE THIS WOULD BE THE BEST EXPERIENCE FOR YOU GUYS!!!!!

DISCLAIMER:- THIS A BIT SMALL ARTICLE AND I'VE ALSO GIVEN LESS TIME TO IT THEREFORE FORGIVE MY MISTAKES.....

1.WHAT CAUSES CAVITIES?

Our mouth contains billions of bacteria which live on our teeth, tongue, etc. Most of these bacteria are usually harmless. A tooth consists of enamel, dentin and pulp.

Enamel is mostly made up of minerals.

Dentin is a layer underlying the enamel. Whereas pulp has blog vessels and nerves.

Now, when we eat foods containing sugars, some of these bacteria feed on the sugars producing acids.

This acid starts to dissolve the minerals of tooth enamel, causing tooth decay. 

Usually, our saliva restores these minerals, thus preventing further decay.

But if we continuosly eat sugary foods then our saliva cannot keep up, causing the bacteria to pass into the dentin and then eventually into the pulp, this creating cavities.

2.In this pandemic period everyone is craving to get vaccine as soon as possible. Why this is taking too much time to prepare? let's learn something about vaccines.

a). HOW DOES VACCINE WORK?

Vaccines train our body to fight against the dangerous disease causing pathogens(a bacterium, virus, or other microorganism that can cause disease).

Vaccines often contain weekend or dear pathogens. When they are injected into our body, they just trigger the immune response but do not cause fully fledged diseases. Our immune cells recognize these pathogens as foreign invaders and thus, produce antibodies. These antibodies kill they pathogens. (More to know:- The was first recognize by a great scientist Edward Jenner while treating the small pox in 1796) Also, the immune cells record the information about the pathogens and the way they were killed. Hence, in case in the future, a similar strong pathogen enters our body, our immune cells remember and easily identify and eliminate the pathogens.

b). Why a vaccine for coronavirus will take longer time to develop?

As the corona virus continues to spread across the globe, the pressure is on for the drug makers to develop a vaccine and bring it to market quickly. As you know Vaccines are preventive medicines they help reduce the risk of catching certain illness and you also know that how does it works on our body by reading the above article. Unfortunately it takes a quite bit of time to develop licence and release a new vaccine ranging from several months to over ten years. Once vaccines are developed in the lab they must go through there phases before they come to market. First phase includes a small groups receive the trial vaccine then in the second phase trial vaccine is given to group of over 100 volunteers and finally in the third phase 1000+ volunteers are given the trial vaccine. As this vaccine is to given to the whole population it is to be accurate and safe so also it shouldn't have any side effects. This is a huge process therefore it takes time to develop.
