Is AstraZeneca vaccine mRNA?The newly reviewed data makes it clear that both AstraZeneca's vaccine, which is known as a viral vector vaccine, and 'mRNA' COVID-19 vaccines, offer equivalent protection against hospitalisation (91.3-92.5%) and death (91.4-93.3%), regardless of age, with no statistical difference.
What are some of the side effects of the COVID-19 Oxford-AstraZeneca vaccine?
Common side effects : Tenderness, pain, warmth, redness, itching, swelling or bruising at the injection site, all of which generally resolve within a day or two. Rare side effects: Some countries temporarily suspended use of this vaccine in March after a small number of recipients developed blood clots and some died.
Are severe reactions to mRNA COVID-19 vaccines common?
We found that reported reactions to mRNA vaccination were mostly mild in severity and transient in duration, and most reports were non-serious. Reactions and health impacts were reported more frequently in female than in male recipients, and in individuals younger than 65 years than in older individuals.
What are the neurological side effects of the Oxford-AstraZeneca COVID-19 vaccine?
For the Oxford/AstraZeneca vaccine, there was a very small increased risk of Guillain-Barré syndrome – a rare disorder in which the body's immune system mistakenly attacks the nerves, triggering numbness, weakness and pain.
Are mRNA boosters effective against COVID-19?In this study, mRNA boosters were highly effective against infection with the delta variant but were less effective against infection with the omicron variant. However, these boosters led to strong protection against Covid-19–related hospitalization and death due to both variants.

How long does the protection from Pfizer and Moderna's COVID-19 booster vaccine last?
The most recent research from the CDC suggests that protection from the Pfizer and Moderna COVID-19 vaccines starts to fade around 4 months after a booster dose.
Is there a COVID-19 second booster for Pfizer and Moderna?
The FDA and CDC have authorized a second booster from Pfizer and Moderna for people with certain immune deficiencies. This includes solid organ transplant recipients and those with conditions that give them an equally reduced ability to fight infections and other diseases.
Can COVID-19 cause other neurological disorders?In some people, response to the coronavirus has been shown to increase the risk of stroke, dementia, muscle and nerve damage, encephalitis, and vascular disorders. Some researchers think the unbalanced immune system caused by reacting to the coronavirus may lead to autoimmune diseases, but it's too early to tell.
What are some of the neurological symptoms of COVID-19?
Neurological symptoms that have been reported with acute COVID-19 include loss of taste and smell, headaches, stroke, delirium, and brain inflammation.
Is guillain barre syndrome a possible side effect of the COVID-19 vaccine?
GBS is one of the possible side effects that might be encountered after the COVID‐19 vaccine. If it occurs, it appears to be responsive to the treatment, and the benefits of administering the vaccine outweigh the risks. The frequency of its occurrence is still needed to be studied.
What are some rare severe allergic reactions to mRNA COVID-19 vaccines?“Overall, severe allergic reactions to COVID-19 mRNA vaccines, including life-threatening anaphylaxis reactions such as low blood pressure and difficulty breathing, are rare, on the order of five cases per million vaccine doses administered,” noted Dr. Guerrerio.
Has anyone had severe reactions to the Moderna COVID-19 vaccine?
Monitoring of the Moderna COVID-19 vaccine has found 10 cases of anaphylaxis after the administration of 4,041,396 first doses of the Moderna COVID-19 vaccine. In 9 out of these 10 cases of anaphylaxis, the recipient of the vaccine had onset of symptoms within 30 min of administration.
Should I be concerned about the potential adverse reactions of COVID-19 vaccines?
The known risks of COVID-19 illness and its related, possibly severe complications, such as long-term health problems, hospitalization and even death, far outweigh the potential risks of having a rare adverse reaction to vaccination like myocarditis or blood clots.
What are the common side effects of the COVID-19 vaccine?The most commonly reported side effects were pain at the injection site, tiredness, headache, muscle pain, chills, joint pain, and fever.
Are long term side effects possible with the COVID-19 vaccine?
Benefits of Vaccination Outweigh the Risks Serious side effects that could cause a long-term health problem are extremely unusual following any vaccination, including COVID-19 vaccination.

How can severe COVID-19 affect the nervous system?
Some people with COVID-19 either initially have, or develop in the hospital, a dramatic state of confusion called delirium. Although rare, COVID-19 can cause seizures or major strokes. Muscular weakness, nerve injury, and pain syndromes are common in people who require intensive care during infections.
How long could the COVID-19 virus linger in your body?But for most infected people, virus levels in the body peak between three and six days after the original infection, and the immune system clears the pathogen within 10 days. The virus shed after this period is generally not infectious.
How long does COVID-19 rebound usually last?How long will a rebound last? In the cases that have been described, rebound symptoms improved and/or positive tests became negative within 3 days for most people.
Does having an autoimmune disease make me more susceptible to COVID-19?However, depending on the autoimmune disorder and the immunosuppressive medication you are taking, you may be more likely to get seriously ill from COVID-19.
What other illnesses are caused by coronaviruses?Coronavirus is a family of viruses that can cause respiratory illnesses such as the common cold, severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS).
How common is Paxlovid rebound of COVID-19?Currently, this type of rebounding appears to be rare. In Pfizers clinical trial, 1 to 2 percent of people treated with the antiviral had a positive COVID-19 test — or an increase in the amount of virus detected — after finishing the treatment.
Is there an authorized booster for the Moderna COVID-19 vaccine?
The FDA-authorized Pfizer-BioNTech COVID-19 Vaccine and the FDA-approved Comirnaty can be used to provide the authorized booster dose(s). Similarly, the FDA-authorized Moderna COVID-19 Vaccine and the FDA-approved Spikevax are authorized to provide the authorized booster dose(s).
Are there any second COVID-19 vaccine booster available?
Recently, the Food and Drug Administration (FDA) and the Centers for Disease Control and Prevention (CDC) authorized a second booster shot of the Pfizer-BioNTech and Moderna vaccines for everyone 50 and older and for people with certain conditions that make them immunocompromised.
Can you mix and match the vaccines for your mRNA (Pfizer or Moderna) primary vaccination series?
No, vaccines used for the primary vaccination series should be same. However, if the mRNA vaccine product given for the first two doses is not available or is unknown, either Pfizer-BioNTech or Moderna COVID-19 vaccine (mRNA COVID-19 vaccines) may be administered.
