The FDA granted emergency use authorization for the Pfizer vaccine on December 11, and by December 13, the first doses were distributed across hospitals nationwide. This moment brought a wave of relief to healthcare professionals who had been battling an unrelenting virus without a clear end in sight. However, as celebrations ensued, numerous questions about the vaccine emerged, often muddled by misinformation and uncertainty. To clarify the facts, we consulted Dr. Michael Reyes, an immunologist with the National Health Network, who is also involved in COVID vaccine trials.
Who Will Be Vaccinated First?
Dr. Reyes explains that the initial recipients will be individuals in high-risk groups, including frontline healthcare workers and residents of long-term care facilities. Following them, essential workers and older adults with preexisting health conditions will be next in line. The general public is anticipated to have access to the vaccine between February and April of 2021.
What Side Effects Can We Expect?
Common side effects include pain at the injection site, fatigue, fever, muscle aches, and chills. Dr. Reyes notes that these symptoms typically resolve within 24-48 hours for most participants in clinical studies. However, individuals with specific allergies should receive the vaccine in a medical setting and be monitored for 30 minutes post-injection. According to a CDC representative, the Pfizer vaccine comprises messenger RNA (mRNA) and four lipid nanoparticles, with no preservatives.
What Should We Know About the Second Dose?
The Pfizer vaccine requires two doses spaced three weeks apart, while the Moderna vaccine, soon to receive FDA approval, has a four-week interval. Both doses are identical, and it is critical to receive both for optimal efficacy. A study published in the New England Journal of Medicine indicated that the vaccine’s efficacy is only 52% between the first and second doses, underscoring the importance of completing the full vaccination regimen.
Is the Vaccine Safe for Those Who Have Had COVID?
Dr. Reyes confirms that individuals who have recovered from COVID-19 and are no longer symptomatic can safely receive the vaccine. Those experiencing lingering symptoms, known as long-haulers, can also be vaccinated, provided they are not exhibiting acute symptoms such as fever or cough.
Can We Return to Normal After the Vaccine?
Not just yet. Dr. Reyes emphasizes that it will take at least six months to vaccinate enough people to significantly reduce infection and transmission rates. Dr. Anthony Collins, a leading infectious disease expert, has suggested that herd immunity could be achievable by next fall.
Are Children Eligible for the Vaccine?
At this time, the Pfizer vaccine is approved for individuals aged 16 and older. Both Pfizer and Moderna are currently conducting trials to evaluate the vaccine’s safety and effectiveness in children aged 12-18.
How Was the Vaccine Developed So Quickly?
Many people are apprehensive about the vaccine’s safety due to its rapid development. Dr. Reyes assures that no safety protocols were compromised. The mRNA technology employed in these vaccines has been in development since the 1990s. The swift progress is attributed to unprecedented global collaboration among scientists and researchers, driven by the urgent need to combat a virus that has claimed over 1.5 million lives worldwide.
Should I Get Vaccinated?
If you do not have any of the aforementioned contraindications, Dr. Reyes strongly encourages vaccination. He points out that for those eager to return to normalcy and recover from the economic impact of the pandemic, the vaccine represents our best hope. With the impending approval of Moderna’s vaccine, we are nearing the end of this protracted global crisis. However, until vaccination efforts ramp up, it remains crucial to continue practicing safety measures such as wearing masks, hand hygiene, and social distancing.
