Original title: FDA is about to approve Moderna’s new corona vaccine and what is the difference between the Pfizer vaccine Source: cnBeta.COM
According to foreign media BGR, an independent review team voted overwhelmingly in favor of an emergency use authorization (EUA) for Moderna’s new crown candidate vaccine.. The team recommended that the FDA issue an EUA for the Moderna vaccine, just one week after making the same recommendation for the Pfizer / BioNTech drug.The agency is expected to issue an emergency use authorization on Friday local time, and vaccination can begin on Monday.
After the Pfizer / BioNTech vaccine received emergency use authorizations in the United Kingdom and the United States, these two countries began receiving the COVID-19 vaccine this month. The EU will soon approve the same medicine and the first group of EU citizens will receive the first dose before the end of the year. Americans will have the opportunity to get the first COVID-19 candidate vaccine because Moderna’s drug just passed FDA Vaccines and Related Biologics Advisory Committee review. On Thursday, the group recommended 20 votes in favor and 0 votes against, suggesting an emergency use authorization for Moderna’s drug candidates. The FDA is likely to issue an emergency clearance on Friday and issue the first dose to the vaccination center by Monday. The two vaccines have many similarities, but there are also many differences between them.
According to the “Guardian” report, by mid-2021 Moderna drugs can be used to vaccinate up to 150 million people. This means that the United States government can carry out successful vaccination campaigns. It is not just logistics that can delay vaccination, but also people who are silent about new drugs.
Both drugs are mRNA drugs for the novel coronavirus peak glycoprotein. The purpose is to teach the immune system to respond to this special characteristic of the virus and to help it infect cells. Once immunity is formed, neutralizing antibodies will block the spike glycoprotein and specialized white blood cells will remember the spike protein.
Both vaccines require two doses and the vaccination time should be several weeks. Also, the efficacy levels and adverse reaction warnings of these two drugs are similar. Pfizer’s drug effective rate for blocking COVID-19 is 95%, while Moderna has a slightly lower effective rate of 94.1%. However, Moderna’s drugs blocked severe COVID-19 in 100% of cases, at least on paper, Moderna has a slight edge.
Both medications require storage and transportation temperatures below freezing, but Moderna medications can be stored at normal freezer temperatures. Pfizer medicines must be transported and stored at minus 70 ° C.
Pfizer’s vaccine has an advantage over Moderna’s vaccine: it can be used in patients up to 16 years of age, while Moderna’s vaccine is effective for adults over 18 years of age. This regulation may result in the government having to persuade more adults to get vaccinated to compensate teens who can’t get medicine this year.
The side effects of the two vaccines are similar, including soreness at the injection site and flu-like symptoms for a few days. The Pfizer drug caused allergic reactions in some patients, a rare event that was not seen in the trial. Moderna’s drug had some allergic reactions in the trial, both in the placebo group and in the vaccine group. A volunteer who received the candidate vaccine developed an allergic reaction more than 60 days after the injection and was linked to a different medical procedure.
