Riya, while we understand your fears, postponing NEET doesnt help you in your Academic year. The Vaccine needs to be brought to India and then 2 doses with a gap of 15 days to billions of people. The administration itself will take atleast the end of this year. But unfortunately we do not get younger. In 2021, we all grow a year older. In the long run, it is going to affect you. At this point in time, all you need to do is trust the Government to conduct the exams in a safe environment. As someone who has been diagnosed positive with Corona and then has been treated to be fit to write this answer to you, personally I can assure you that things will get better. Not all the front care professionals are falling sick. And if the Centre has taken a decision, it is in the larger interest of the Students. So at this point in time, all we can do is take precautions and go with the flow. This year, along with your Admit Card and Valid Id proof, you should also carry your Mask, Head gear, gloves and a sanitiser to be careful. Also take an passport size photographs along with your admit card. NTA released the following protocols:

• Contact less frisking will be ensured.
• Time slots will be staggered for Reporting to the exam
• Contact less verification of documents
• Candidates will have to carry a self declaration regarding their Corona free health status
• Candidates with more than required body temperature will be allowed to take the exam in isolated rooms

And then you need to report to the exam hall atleast an hour before the exam for checking.
