How do the four largest COVID-19 vaccines not available in the US compare to those available

Vaccinations from the UK, Russia, China and India are used elsewhere to fight COVID-19.
But it is not available in the US, which only US companies approve.
Here’s how to compare statistics, such as ease of transportation, efficiency and cost.

The US granted three types of COVID-19 shots for vaccination: the shots Pfizer, Moderna and Johnson & Johnson. But this is not the only option.

Other vaccines are used around the world and are likely to vaccinate more people around the world than those used in the US.

Non-US shots include Sputnik V (made in Russia), AstraZeneca (made in the UK), Sinovac (from China) and Covaxin (made from India).

Here’s how they compare to US approved vaccines on four key statistics:

EFFECT

Pfizer (US): 95%
Approved by the FDA and reinforced by positive actual data.
Modern (US): 94.1%
Approved by the FDA, also supported by good actual data.
Johnson & Johnson (USA): 66%
Trial results are not published, but they have been approved by the strict FDA.
AstraZeneca (United Kingdom): 62% (although the figure is less simple than the others)
Authorized by Europe’s EMA Agency and dozens of others around the world.
Sputnik V: 91.6%
Authorized in more than 40 countries, although not US, EU or UK.
Sinovac: Unclear. One trial said 50.4% and another 91.2% said.
Authorized in at least 15 countries, including Mexico, Turkey and Thailand.
Covaxin: 81% – claim it. There is no published data, which makes it difficult to say for sure.
Only authorized in India, Iran and Zimbabwe.

Efficacy data are only one way to measure whether a vaccine works, and different test results are not strictly comparable.

As long as a vaccine is safe and has an efficiency above 50%, experts believe that it is useful to combat COVID-19.

Price figures can vary depending on the location and who buys, so the following is approximately:

* Johnson & Johnson’s is a one-vaccine vaccine and therefore requires half as many doses as the other vaccines.

Pfizer and Modern: Both vaccines use brand new mRNA technology.
Johnson & Johnson, AstraZeneca, Sputnik V: These three use the proven combination of an adenovirus (a harmless virus shell) and DNA.
Sinovac, Covaxin: These two use a disabled version of the coronavirus, modified so that it can not make people sick.

(This determines whether vaccines can reach remote and rural areas safely, especially important in poorer countries.)

Pfizer: 6 months at about -95 ° F, 5 days at about 35 ° F, 2 hours at room temperature.
Modern: 7 months at -4 ° F, 30 days at about 35 ° F, 12 hours at room temperature.
Johnson & Johnson: 3 months at about 35 ° F, 12 hours at room temperature about 70 degrees.
AstraZeneca: 6 months at about 35 ° F.
Sputnik V: 2 months at about 35 ° F.
Sinovac: up to three years at about 35 ° F.
Covaxin: about 35 ° F.

It depends. Some manufacturers may not be interested in the US market, which is being served better than almost anywhere else.

AstraZeneca has said it will seek approval for the vaccine from the US FDA within the next few weeks.

In contrast, a Sputnik V representative told Insider in February that the company had little interest in the U.S. market.

As for Covaxin and Sinovac, it is not clear if they want to apply to the FDA. The Indian and Chinese vaccines are being distributed elsewhere.

Meanwhile, all the experts say that the best vaccine you can get is the one you are offered.
