Now, eight months since the coronavirus pandemic has struck, the majority of the world’s population is vulnerable.By preparing people’s immune systems to combat the infection, a vaccine will have some protection so that they would not get ill. This would make lifting lockdowns more safe, and calming social distance. Research is at a breakneck pace. Around 140 are in early production, and only two dozen are currently being tested in clinical trials on humans, experts and scientists are trying all they can to develop an effective and safe vaccine and ensure safety of coronavirus vaccine. The vaccine development for coronavirus is already passing Multiple research groups have planned new vaccines but much further work needs to be done.

• Tests and trials will need to prove that the vaccine is effective. It would be unsuccessful if it caused more problems than the disease
• Clinical research would also need to demonstrate immune response from vaccinations that prevent people from becoming sick.
• A way to manufacture the vaccine on a massive scale needs to be created for the billions of possible doses
• It must be licensed by Medicines Regulators before it can be given
• Lastly, the massive logistical obstacle of actually immunizing the majority of the world ‘s population all the records for previous pandemic vaccines. 

The FDA recently released guidelines on the development of vaccines for COVID-19. The guidelines they gave to manufacturers of vaccines —a guideline open to the general public — is that a vaccine will need to be effective at least 50 per cent.Anyone who is participating in the study receives complete details about the types of acute symptoms you can expect following an infection. People may need to include details about the injection site’s swelling, redness, tenderness, fever, and any other symptoms they may encounter in the three to seven days following vaccination.

Once WHO and other health organisations ensure safety of coronavirus vaccine or a vaccine candidate it would be important for it to be accessible to those who need it. Healthcare professionals who come into contact with COVID-19 patients will top the list. The disease is most lethal in the elderly so if the vaccine was successful in this age group they would be a priority. Other people who are deemed at high risk-possibly including those with certain disabilities or chronic ailments will be given priority.
