Here are what you should know about the Johnson & Johnson Covid-19 vaccine. The first one-dose vaccine authorized in the United States. During the first quarter of 2021, the pharmaceutical giant Johnson & Johnson (J&J) released its vaccine to combat COVID-19.
The J&J vaccine, which the company’s pharmaceutical arm Janssen developed, differs in formulation from the Pfizer and Moderna (mRNA) vaccines and only needs to be administered once. The FDA has approved the J&J vaccine for use in healthy adults over the age of 18. (FDA).
However, the CDC has restricted vaccine availability due to safety and efficacy concerns and suggests that, barring exceptional circumstances, you acquire the Pfizer or Moderna vaccination instead of the J&J vaccine. Those with a severe reaction to an mRNA vaccination dosage or who have restricted access to the mRNA vaccine options are among those who the CDC recommends only consider the J&J vaccine.
Compare and contrast the J&J vaccine to those of Pfizer and Moderna.
Pfizer and Moderna’s vaccines were developed in a different way than the one developed by Johnson & Johnson. For starters, it’s a single shot rather than a pair at first.
The J&J vaccine is not an mRNA vaccine but rather adenovirus-vectored. This is a technical term for a vaccination in which the genes for making viral proteins from coronaviruses are hitchhiked onto a common cold virus (also known as an adenovirus).
This may be why studies have indicated that the J&J vaccination is less effective than others on the market. Hospitalization rates due to the Delta form have increased by the mid-90s, thanks to both the Moderna and Pfizer vaccines.
According to a study of South African healthcare personnel, the vaccine made by J&J has been shown to prevent 71% of hospitalizations caused by this strain. Healthcare professionals are more likely to contract the disease than the general population, making it challenging to make direct comparisons between the vaccinations’ success rates.
At this time, the CDC advises against using the J&J vaccination and instead uses the mRNA vaccines (made by Moderna or Pfizer). A larger chance of adverse effects in J&J’s product is a major factor in why it is less popular.
But it’s important to remember that J&J’s vaccine completely prevented deaths from COVID in early clinical trials after only 28 days. Recent studies conducted on healthcare workers in South Africa have shown that the J&J shot can prevent up to 96% of deaths caused by the Delta strain.
The FDA has only formally approved the Pfizer and Moderna vaccines outside of emergency use authorization. This further medical scrutiny is what’s required for full FDA approval.
The FDA approved booster doses for everyone 18 and older two months after the original J&J vaccination injection. For these CDC-recommended booster shots, it is acceptable to “mix and match” doses of Pfizer and Moderna vaccines.
Those who received a booster dose after receiving the J&J vaccine had nine times greater levels of COVID-19 antibodies than those who just received the initial vaccination.
Does J&J Have a Safe Vaccine?
Yes. Some people who have had reactions to other vaccines or chemicals may be able to use the Johnson & Johnson vaccine instead. Studies have shown that the J&J vaccination causes less severe adverse responses, such as anaphylaxis than competing vaccines.
Even yet, two major adverse effects have been documented in persons who received the J&J vaccine. Although these events are uncommon, the consequences can be devastating.
The consumption of the J&J vaccine was halted to undertake a full safety study following reports of six persons developing a rare and severe type of blood clot after getting the vaccination. The suspension was quickly lifted after the Food and Drug Administration, and the Centers for Disease Control and Prevention assessed that the vaccine was safe and effective for use in the United States.
At least 57 patients who received the J&J vaccine have reported symptoms of blood clotting syndrome (of which more than 17.7 million doses have been given in the U.S.). Nine of them certainly perished. In comparison, out of 513 million doses of mRNA COVID vaccinations, only three incidences of blood clotting have been reported.
If the Pfizer or Moderna vaccinations are unavailable, the CDC advises that the advantages of the J&J vaccine still exceed the dangers. Women between 30 and 49 are specifically encouraged to consider getting the Pfizer or Moderna vaccine if they are worried.
Guillain-Barré Syndrome (GBS).
Muscle weakness and numbness occur as a result of an immune system attack on the nervous system, which is the underlying cause of this disorder. Paralysis and permanent nerve damage are other complications of GBS.
According to the CDC, at least 302 cases of GBS have been discovered in patients who received the J&J vaccine. The vast majority of those afflicted were men over the age of 50, and they frequently developed GBS symptoms two weeks after taking the vaccine.
The CDC has discovered no link between GBS with either the Pfizer or Moderna vaccinations.
Despite an increased risk of some adverse outcomes, the J&J vaccination may be a useful choice for persons who are allergic to or have had a severe response to the components in mRNA vaccines.
If you’re not sure which option is best for you, consult a doctor.
Should a Pregnant Woman Get the J&J Vaccine?
No adverse effects of the COVID vaccination on pregnancy have been observed in studies performed yet. Although the J&J vaccination is not recommended, the alternatives from Pfizer and Moderna are.
Some worry that a placental immune response is possible because the coronavirus spike protein shares short segments of its genetic code with placental protein. In any case, the placental protein is structurally distinct from the other proteins, and the vaccine does not cause an immune response against it.
COVID-19 immunization is recommended for pregnant and trying-to-conceive women by the American College of Obstetricians and Gynecologists (ACOG), the Society for Maternal-Fetal Medicine (SMFM), and the American Society for Reproductive Medicine (ASRM).
Although ACOG has concluded that the J&J vaccination is safe for pregnant women, it recommends that women try Pfizer or Moderna’s vaccines instead. Researchers have shown that mothers who have tested positive for COVID-19 are at a much-increased risk of developing serious pregnancy problems.
Furthermore, studies have shown that COVID-19 vaccinations appear to provide your newborn with protective antibodies against COVID. Both of these points highlight the need to think about obtaining the vaccine while pregnant.
The CDC advises pregnant women with concerns about the COVID-19 vaccine to contact MotherToBaby, where they can speak with specialists from the nonprofit Organization of Teratology Information Specialists (OTIS). Get in touch with us via our toll-free hotline (1-866-626-6847) or online chat.
The Future of My Children
These immunizations are currently restricted to those aged 18 and up only. The Pfizer and the Moderna vaccines are safe for children 6 months and older. Vaccinating kids against COVID-19 is the first line of defense against the disease, as the American Academy of Pediatrics (AAP) recommended.
The American Academy of Pediatrics (AAP) says it’s fine for kids to have the COVID vaccine at the same time they get their regular shots.
Until the vaccine has been demonstrated to be effective and safe for younger teens and kids, it will not be given to children, who were not included in the early J&J clinical studies.
Johnson & Johnson announced the start of testing its vaccine on 12-17 year olds on April 2, 2021. It is unknown whether or if the corporation will conduct tests on newborns, pregnant women, or others with impaired immune systems.
Fortunately, there is mounting evidence that, if infected, children will display milder signs of COVID than adults. Pfizer or Moderna vaccines are the best options, nevertheless.
