The CDC has really useful a brand new COVID-19 vaccine: Novavax.
Why it issues
Novavax is the primary protein-based vaccine for COVID-19 accessible within the US, although protein-based vaccines have been round for many years.
What it means for you
If you have not obtained any COVID-19 vaccine but, you may get Novavax.
Novavax, the fourth COVID-19 vaccine to be accessible within the US, will quickly be an possibility for adults who have not but been vaccinated in opposition to COVID-19. About 10% of individuals aged 18 and older have not obtained any dose of a COVID-19 vaccine.
The US Facilities for Illness Management and Prevention really useful Novavax as a main sequence vaccine Tuesday,from a bunch of scientific advisers that provides steerage to the CDC. This was the ultimate barrier for Novavax, and the vaccine will likely be accessible at pharmacies all through the US within the coming weeks.
As a result of it is licensed solely as a main sequence and never a booster shot, the brand new vaccine cannot be used as a booster but in individuals who’ve already been vaccinated. And although Novavax’s preliminary affect could also be restricted due to this, its availability will give those that’ve been holding out for a protein-based or extra “conventional” vaccine an alternative choice. Vaccine sorts like Novavax have been round for greater than 30 years, based on the CDC, and used in opposition to shingles, the flu and extra.
Greater than two years into the pandemic, the variety of people who find themselves absolutely vaccinated hasn’t modified very a lot in latest weeks, and people hesitant about vaccination appear to be agency of their stance, based on a ballot from the Kaiser Household Basis. The proportion of American adults who answered the ballot who stated they might “positively not” get a COVID-19 vaccine ranged from 15% in December 2020 to 17% in April 2022.
Apart from Novavax, there are three different licensed or really useful COVID-19 vaccines in the marketplace within the US, and two of them are nonetheless broadly really useful for adults. (The Johnson & Johnson COVID-19 vaccine continues to be licensed within the US, however its use has beendue to a uncommon however severe danger of blood clots. This leaves Pfizer’s and Moderna’s vaccines as the opposite two at present really useful choices for adults.)
“It is good to have a vaccine on board like Novavax as a result of it is an alternative choice for people who may need contraindications to the opposite vaccine platforms,” Ross Kedl, a professor of immunology and microbiology on the College of Colorado Anschutz Medical Campus, stated in an e-mail. “Some have allergic reactions or extra uncommon issues like blood clots.”
Novavax has been a very long time coming. The corporate had a contract with the federal authorities by means of Operation Warp Velocity however has skilled manufacturing issues which have hindered a speedy emergency use authorization. Its COVID vaccine is already accessible in different nations, together with Canada and Australia, beneath the identify Nuvaxovid.
Here is every little thing we all know.
When can I get a Novavax shot?
The Novavax rollout is slightly completely different than earlier booster or vaccine rollouts, which made pictures accessible to individuals nearly instantly after the ultimate sign-off by CDC Director Dr. Rochelle Walensky. (In Novavax’s case, there was no “preordering” of vaccine doses.)
Primarily based on the CDC’s planning doc for Novavax, we will anticipate to see doses of Novavax out at US pharmacies as early as the top of July or the primary week in August, Kristen Nichols, pharmacist and senior content material administration guide at Wolters Kluwer, stated in an e-mail. However the timeline might additionally depend upon the place you reside.
“We will not make a precise willpower on when doses will likely be accessible, notably in additional rural areas the place cargo might take longer to achieve all care facilities,” Nichols stated.
To verify when and the place Novavax is on the market close to you, you should utilize the COVID-19 vaccine finder to pick out your most well-liked vaccine kind.
Who can get Novavax?
Novavax’s COVID-19 vaccine is for adults who have not obtained any COVID-19 vaccine but. It is licensed as a two-dose main sequence for adults age 18 and up, with every dose sometimes given three weeks aside.
As a result of it is licensed as a main sequence, individuals who’ve already been vaccinated cannot get it as a further shot or booster proper now. However because the FDA has licensed amethod with different COVID-19 vaccines up to now, Novavax’s authorization could also be prolonged to extra individuals sooner or later.
As is the case with some other drug or vaccine, individuals with allergic reactions to an ingredient in Novavax should not take it, says Nichols.
Whereas Novavax’s main sequence is the one one licensed now, it is doable that Novavax might have a brand new, omicron-specific booster prepared this fall or winter. After the FDA introduced its plans for the, Novavax stated it is dashing up work on an omicron-specific vaccine that targets the super-contagious BA.5. However like the opposite new, future vaccine, the FDA might want to authorize this individually.
What’s Novavax? How is it completely different?
Novavax is a COVID-19 vaccine that makes use of a extra conventional protein-based know-how, not like the opposite vaccines at present accessible within the US: Pfizer-BioNTech and Moderna use mRNA know-how, and Johnson & Johnson is a viral-vector vaccine.
Within the Novavax vaccine, a purified protein of the virus is combined with what’s known as an adjuvant — components that “get up the immune response and inform it to take this goal severely,” Kedl stated.
Dr. Glenn Wortmann, an infectious illness specialist with MedStar Well being, stated the final method of most vaccines is to make use of a protein base.
“Particularly, Novavax is similar to the hepatitis B vaccine” that almost all of us obtain as kids, Wortmann stated. Some vaccines for influenza, shingles and different illnesses use the same know-how.
Whereas it provides an alternative choice, nevertheless, the jury could also be out on whether or not Novavax provides superior immunity to Pfizer’s and Moderna’s vaccines.
“Immunologically talking, for my part it does not likely convey an terrible lot by itself to the desk that’s not already well-addressed by the mRNA vaccines,” Kedl stated.
Nonetheless, it’s simpler to retailer and ship than mRNA vaccines, he stated. This can be a bonus when vaccinating harder-to-reach communities the place retaining finicky vaccines cool within the fridge could also be tough. However Novavax has severe disadvantages with regards to manufacturing, Kedl stated, as a result of it is not low cost for the corporate to supply and purify the proteins.
“mRNA vaccines skip that step as a result of they flip every particular person into their very own vaccine producer,” he stated. mRNA vaccines work by instructing our cells to make the protein themselves that may set off an immune response.
For that reason, mRNA vaccines are simpler to regulate than Novavax when a brand new variant comes alongside, Kedl stated.
“The mRNA platform is way extra modifiable than what Novavax does,” he stated. “Each time a brand new variant vaccine must be made, Novavax goes to need to do plenty of work within the lab to determine which adjustments will nonetheless enable an excellent protein to be made and purified at mass portions.”
How efficient is Novavax?
Revealed outcomes from a trial discovered that Novavax was greater than 90% efficient in opposition to symptomatic COVID-19, and 100% efficient in opposition to extreme illness and loss of life. However importantly, that trial was carried out earlier than the omicron or delta variants have been broadly circulating. Each the delta and omicron variants — together with omicron subvariant BA.5 — are extra contagious and evade some immunity from vaccines and prior an infection.
Actual-world knowledge evaluating the effectiveness of Novavax to different vaccines would not exist but. Per the World Well being Group, “It’s unimaginable to match vaccines face to face because of the completely different approaches taken in designing the respective research.”
What are the unwanted side effects of Novavax?
Like with different vaccines, unwanted side effects after getting the Novavax vaccine are sometimes delicate, widespread and occur inside seven days of getting the shot, based on the CDC. Examples are tiredness, fever, chills and a headache, which clear up inside a few days. These are indicators your immune system is reacting and mounting a protection.
Myocarditis and pericarditis (irritation of the guts) is a uncommon aspect impact. Six out of roughly 40,000 vaccine recipients developed it in a medical trial with Novavax, in contrast with one within the placebo group.
