4 months ago (on Nov 18, 2020)
On Monday, the company Moderna announced it had a Coronavirus vaccine. The vaccine is 95% effective and is good for both young and old people.
The vaccine can be stored in a refrigerator at 2C to 8C degree for 30 days. It can also be stored for 6 months at -20C degree.
A person needs to take 2 doses for it to be effective. Moderna hopes to produce 1 billion doses by the end of 2021. The vaccine will cost $35 to $37 per dose.
Last week, another company, Pfizer, also announced its own vaccine. Now the government needs to approve these vaccines before people can buy them.
