The Food and Drug Administration approved Moderna’s coronavirus vaccine for emergency use on Friday. The vaccine is the second to be approved for use in the United States, after Pfizer and BioNTech vaccine in the United States. The potentially life-saving shots are essential to keep off the pandemic that has claimed more than a million lives worldwide, and crippled healthcare services.Let’s have a look at the similarities and differences between the two vaccines.

Similarities

  • Both the vaccinations require two doses.
  • Both vaccines use messenger RNA (mRNA) technology, which gives human cells directions to produce proteins that resemble the coronavirus protein. The principles drive the immune system into operation, which provides a blueprint for specific and necessary antibodies without infecting users with COVID-19.
  • To stimulate an immune response, the vaccines use parts of the encoded protein. As a consequence, the SARS-CoV-2 antibodies, that is, proteins produced by your immune system to help combat possible diseases of the virus. When your body has the immune response, both the protein and mRNA are removed, while the antibodies remain to safeguard you for the future. Incase you have contracted the virus and cannot pay the high medical bills here’s what you can do.

Differences

Dosage: For those receiving Pfizer, the second dose is given 21 days after the initial dose. Moderna’s double dose is given 28 days after the first dose.

Efficacy: According to the FDA, Moderna vaccination was 94.1 percent helpful in reducing symptoms in patients. The Pfizer vaccine stated 95 percent efficacy.

Genetic structure: The two vaccinations are identical, but not the same. Both consist of genetic material, mRNA, covered in a lipid bubble. The exact chemical structure is not the same, so it is not sure if an allergic reaction to one will affect the other. But the probability is a subject of concern.

Storage: Pfizer’s coronavirus vaccine should be kept at super temperatures of just around -70 degrees Celsius (-94 Fahrenheit). It can only be refrigerated for five days after thawed. To maintain it at the correct temperature, the vaccine needs a particular shipping container filled with dry ice.

Moderna can be preserved for up to six months at standard freezing temperatures of -20 Celsius (-4 Fahrenheit). Like any other regular vaccine, it can be stored in a refrigerator for up to 30 days after it’s thawed.

Age group: Pfizer vaccine has been approved for people aged 16 and over. Moderna’s vaccine was approved by the FDA Emergency Use Permission Panel for adults, 18 and over.

Side effects:

  • No significant long-term side effects resulted in either of the two large-scale clinical trials of the vaccines. But there are significantly different short-term side effects noticed.
  • Side effects were usually moderate and transient with both the Pfizer and Moderna vaccines, including irritation at the site of injection, cough, fever, weakness, chills, and muscle and joint pain.

More information is required to clarify just how effective either vaccine is at controlling the virus’s spread. Although these are incredibly successful at preventing symptoms and severe infection, we do not know whether anyone is protected from being infected by them. Experts claim that masks will still be required to ensure that vaccinated individuals do not transmit the virus until that is understood.

U.S. authorities plan to vaccinate at least 20 million Americans — mainly front-line health care staff and nurses — by the end of the year. Initial shots will be limited as production speeds up, with authorities estimating that it will take months to immunize everyone in the U.S. who wishes to be vaccinated. The CDC-Centers for Disease Control and Prevention has issued guidelines that advise prioritizing health professionals and nursing homes, but states may administer the vaccine however they see appropriate.

Moderna and Pfizer have also predicted millions of doses to be available by early 2021. But the world’s population is 7 billion, and everybody will require two doses of these vaccines.

The EUA for Moderna COVID-19 Vaccine has been given to ModernaTX, Inc. The authorization will be valid until a decision has been made that conditions justify the emergency use of medications and biologics to treat and prevent COVID-19. The EUA for Moderna COVID-19 Vaccine may be amended or withdrawn, if it is decided that the EUA no longer satisfies the issuance’s regulatory requirements. Meanwhile, Pfizer/BioNTech has applied for EUQ in Japan.

The FDA, an agency of the U.S. department, safeguards public health by ensuring the security, efficacy, and safety of veterinary and human medications, vaccines, and other biological products for human use and medical devices. The Department is also responsible for the protection and security of the food supplies, cosmetics, dietary supplements, products that release electrical radiation, and the enforcement of tobacco products.

The Indian government has ensured that the Covid-19 vaccine will only be launched after being safe. According to the document, moderate fever and discomfort at the injection site can be typical side effects in some patients. The Centre has requested state governments to make preparations to cope with any side effects associated with Covid-19 vaccines as one of the safe mass distribution steps for vaccines.

Conclusion

In immunizing hundreds of millions of persons, many challenges will need to be addressed. How long safety from future shots will endure, and how many persons would refuse to take up the injection is still uncertain. Health advocacy groups fear that growing concerns about Covid vaccines could disrupt the implementation. There are also limitations in increasing production and delivering doses.
