Pfizer-Covid Vaccine: Supportive side effects include swollen lymph nodes

[ad_1]

Millions of people across the UK are being offered a booster dose of the Pfizer or Moderna vaccine to increase their protection against Covid before winter. The concern is that the dual threat of influenza and coronavirus will overwhelm the NHS. The decision to give a lightly booster dose was not made.

Health authorities came to the decision after analyzing data from clinical trials, and making sure there were no safety concerns that made the decision out of proportion to the Covid threat.

Although regulatory agencies have concluded that an enhanced dose of protection is obtained without causing harm to recipients, side effects have been reported.

Some of the more interesting insights emerged from the Food and Drug Administration (FDA) analysis, which was a prerequisite for the launch of Pfizer Booster in the United States.

The FDA analyzed safety and immune response data from a subset of participants from the original Pfizer-BioNTech COVID-19 vaccine clinical trial.

In addition, consideration was given to real-world data on vaccine efficacy over a sustained period of time provided by both US and international sources, including the CDC, UK and Israel.

Safety was assessed in 306 participants aged 18–55 years and 12 participants aged 65 years and older who were followed for an average of more than 2 months.

The Food and Drug Administration stated, “It is noteworthy that swollen lymph nodes in the axillary area were observed more frequently after the booster dose than after the first two dose series.”

The most common side effects reported by clinical trial participants who received a booster dose of the vaccine were pain, redness, and swelling at the injection site, as well as fatigue, headache, muscle or joint pain, and chills.
