Vaccines from the UK, Russia, China and India are being used elsewhere to combat COVID-19.

But they are not available in the United States, which only authorized jabs from American companies.

The United States has authorized three types of COVID-19 vaccines for the launch of the vaccine: the Pfizer, Moderna and Johnson & Johnson vaccines. But they are not the only options.
Around the world, other vaccines are being used and are likely to end up inoculating more people around the world than those used in the United States.
Images outside the US include Sputnik V (made in Russia), AstraZeneca (made in the UK), Sinovac (from China) and Covaxin (from India).
Here’s how they compare to vaccines approved in the U.S. on four main indicators:
EFFICIENCY
-
Pfizer (USA): 95%
Authorized by the FDA and supported by positive real-world data. -
Modern (USA): 94.1%
Authorized by the FDA, also based on reliable real-world data. -
Johnson & Johnson (USA): 66%
The test results were not published, but it obtained authorization from the strict FDA. -
AstraZeneca (United Kingdom): 62% (although the number is less direct than the others)
Authorized by the EMA agency in Europe and dozens of others around the world. -
Sputnik V: 91.6%
Authorized in more than 40 countries, but not in the US, EU or UK. -
Sinovac: It is not clear. One study said 50.4% and another 91.2%.
Authorized in at least 15 countries, including Mexico, Turkey and Thailand. -
Covaxin: 81% – affirms. There are no published data, which makes it difficult to say for sure.
Authorized only in India, Iran and Zimbabwe.
Efficacy data is just a way of measuring whether a vaccine works, and different test results are not strictly comparable.
As long as the vaccine is safe and effective over 50%, experts say it is useful in combating COVID-19.
PRICE PER DOSE
Price values may vary depending on location and who is buying, so the following are approximate:
* Johnson & Johnson is a single injection vaccine, so it requires half the doses of other vaccines.
TECHNOLOGY
-
Pfizer and Moderna: Both vaccines use entirely new mRNA technology.
-
Johnson & Johnson, AstraZeneca, Sputnik V: These three use the tried and tested combination of an adenovirus (a harmless virus shell) and DNA.
-
Sinovac, Covaxin: These two use a deactivated version of the coronavirus, modified to keep people from getting sick.
STORAGE AND TRANSPORTATION FACILITY
(This determines whether vaccines can safely reach remote and rural areas, especially important in the poorest 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 around 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: around 35 ° F.
When will these vaccines be available in the USA?
It depends. Some manufacturers may not have an interest in the US market, which is already better served than anywhere else.
AstraZeneca said it will seek approval for its US FDA vaccine in the coming weeks.
On the other hand, a Sputnik V representative told Insider in February that the company has little interest in the US market.
As for Covaxin and Sinovac, it is not clear whether they would seek to apply for the FDA. Both the Indian and Chinese vaccines have been widely distributed elsewhere.
In the meantime, all experts say that the best vaccine to obtain is the one that was offered to you.
