Microsoft founder Bill Gates appreciated the release of final stage clinical trial data for the Pfizer and Moderna vaccines. They were more than 90% effective against Covid-19. Even so, he remains worried about the distribution of vaccines in order to end the corona pandemic.
According to Bill Gates, several other Covid-19 vaccine candidates are likely to show a strong level of efficacy (efficacy) to protect humans from Covid-19 infection.
“With good news from Pfizer and Moderna, we think the AstraZeneca, Novavac, and Johnson & Johnson vaccines are likely to show strong efficacy,” he said as quoted by Business Insider, Friday (20/11/2020).
Bill Gates worries about vaccine distribution
Even though scientists have discovered Covid-19 vaccine, Bill Gates was worried about the distribution of the vaccine. One of the highlights by him is the United States. He assessed that up to now there has been no adequate guide for the distribution process.
Vaccine distribution process is not an easy thing. The problems range from getting the vaccine to the person who needs it most. Like tracking the two doses given to making sure the vaccine doesn’t expire because of having to keep it cold.
“I am worried that the vaccine is not distributed to the right people and will not run quickly. You may have expired vaccines because the distribution of vaccines is not maintained by the cold temperature,” he was quoted as saying by the Boston Globe.
Refrigerators will indeed play a role in vaccine distribution because the vaccines currently being developed require a certain temperature to remain stable. Not to mention the relatively short user time so it must be distributed.
Vaccines need a cold place
The Covid-19 vaccine made by Pfizer and BioNTech makes a storage area with a temperature of minus 75 degrees Celsius. Unfortunately, not many health facilities have it. This vaccine also can only last for 5 days in the cold room.
The Moderna vaccine requires a refrigerator with a temperature of 2-8 degrees Celsius and the vaccine can last for 30 days. If stored in a cupboard with a temperature of minus 20 degrees Celsius, the vaccine can last for 6 months.
