Studies show that the J&J vaccine protects against the delta variant too


I hope everyone who celebrates the 4th had a nice holiday weekend. We actually had another family over, ate food, laughed and felt somewhat like normal people. But it’s been so long, we were exhausted by the end of it. Reentry is going to take a while. And it must still be moderated because, even though we are vaccinated and wearing masks in crowds, COVID is not leaving us just yet. This Delta variant has come to play. It is now the number one strand here in California. I’m back to wearing a mask on my morning walks. However, most studies say I am still pretty safe with my double dose of Moderna protecting me, as is my Pfizer protected family. But what about our single dose Johnson & Johnson friends? According to CNN, they don’t have to worry about the Delta variant for a while.

The Johnson & Johnson coronavirus vaccine provides immunity that lasts at least eight months, and it appears to provide adequate protection against the worrying Delta variant, the company said in a statement Thursday night.

“Current data for the eight months studied so far show that the single-shot Johnson & Johnson COVID-19 vaccine generates a strong neutralizing antibody response that does not wane; rather, we observe an improvement over time,” Dr. Mathai Mammen, head of research and development at J&J’s Janssen vaccine arm, said in a statement.

The company said one dose of the vaccine elicits both a lasting antibody response and generates immune cells called T-cells that last eight months, also.

Earlier Thursday, J&J said a second or booster dose of its vaccine would not be necessary.

Dr. Anthony Fauci agreed. “With regard to the idea of boosting, there’s a lot of talk about that — but right now I think we still need to remember that in fact, the J&J vaccine is a highly effective vaccine that has been recommended very clearly and has received an emergency use authorization,” Fauci, who is director of the National Institute of Allergy and Infectious Diseases, told a White House briefing Thursday.

However, J&J, along wit the US National Institutes of Health, is testing to see whether giving people two doses of its vaccine will provide better protection.

It should be noted that Pfizer and Moderna say their vaccines give at least six months of protection, even though studies have indicated that two doses might protect a person for much longer. J&J is also promising with eight months. Anyone who has had the recommended doses for any of the vaccines should feel good about their protection against the Delta variant. Remember, that does not mean you won’t get it, but the chances are lower and the effects will be far less devastating if you do.

With things moving forward on the vaccine front, people are starting to look ahead at boosters that most of the vaccines companies have predicted around the end of the year. One question emerging is whether we will be able to cross brands, as in can I get a Pfizer boost if I am a Moderna vaxxer? At this point, the major health organizations say the focus needs to be on people getting properly and fully vaccinated without skipping the second dose if it’s required. The medical community is working on all of the booster information now, with trials and tests, and will let us know later in the year. Right now, much of the information is speculative. Booster information is irrelevant if a person has not been properly vaccinated initially, so they are concentrating their efforts on that for the time being. But the booster rollout will be as informed as the vaccine rollout when the time comes.

    I honestly would have been so happy with a J&J shot. I’m terrified of needles and almost went through a panic attack while sitting for my first Pfizer shot and I still have to get my second shot in August. Once was bad enough and I’m dreading going through that a second time.

    • anon says:

      Lauren- I got the J&J shot in late march for the same reason and it hurt like hell, I also got sicker than I’d gotten in years. Two weeks ago I consulted my doctor and she recommended getting a Pfizer shot asap because there was no data about its effectiveness against the delta variant. The Pfizer shot didn’t hurt all all initially, my arm was a little sore for a couple days, I had a headache and some body aches. But that was nothing compared to the J&J… I had the worse chills (I’ve never been so cold), injection site pain, headache, body ache, nausea and vommiting. It sucked.

  2. MsIam says:

    I got the J&J shot before it was pulled. I’m glad to hear it looks good against the Delta variant too.

    • lemonylips says:

      I’m glad I got it. Finally, 3 weeks ago. And these studies sound promissing. I just wish people would get vaccinated more here in EU. So many are refusing to do so. I have to admit I felt so much better psychologically after getting it, although I still wear a mask and avoid the crowds and will continue to do so. Just seem like I’m in a big minority atm.

    I live in Canada, and you can definitely alternate what kinds you get. My first dose was Pfizer, and I’ll be getting Moderna this upcoming Thursday for my second dose :)

    • detritus says:

      Anecdotally, mixing vaccines seems to give you a higher chance of side effects. Your still safer quicker though.

      I’d be interested to hear how yours goes

    Woo-hoo! I got this vaccine but I am still wearing my mask and taking precautions.

    • LillyfromLillooet says:

      I’m vaccinated. I don’t mask up anymore unless required and also when I realized that sales staff in some stores were sneaking looks at maskless me and that I was causing them anxiety.

      A friend who was vaxxed got Covid (was exposed to an unvaxxed carrier) and experienced it as a mild cold that lasted three days.

  5. Maria says:

    I got both shots of Pfizer. I’m waiting to see if there is any research on maybe getting a full dose of a second vaccine. I would be happy to get both shots of the Moderna or J&J too if it is possible. Still double masking and distancing when I can.

  6. isabel says:

    My friend down in San Diego is vaxxed but a relative was infected and got the whole family (and her) sick at a graduation party, so I’m pretty sure it was the delta variant. I’m in the bay area so I keep my mask on all the time in public. I love my mask!

  7. FHMom says:

    Life is seeming normal again for me. I dont think I’ll be comfortable in a crowd for a while, if ever again. Even pre-Covid, I avoid crowds.

  8. Cee says:

    I got this vaccine at the MIA airport exactly a month ago. I had no side effects and I’m getting an antibody count test this Saturday just to see if my body reacted to it or not.
    My dad got the chinese vaccine and his antibody count was so high, we were all surprised (and relieved).

    Still I wish more people kept masking and socially distancing* from people not within their bubble. We can still get the virus and spread it. Kids under 18 are still not vaccinated. People with illnesses incompatible with most vaccines are still at risk. Now is not the time to stop taking precautions. This virus is way too smart and keeps changing.

    *standing 2 feet apart.

  9. Size Does Matter says:

    Until my 5yo and 8yo can get vaxxed I will continue to wear that mask like it’s my job. I have no idea what I will do in August when school starts since our lovely governor Greg Abbott ordered that school districts cannot have mask mandates. And our school district isn’t offering an online option this school year.

    The omega version just is the news and it is more infectious and deadly than the delta and so far it looks like none of the vaccines are veer effective against it. Seriously, it is terrifying. And it is here in the US already. I think we all should just stay at home as much as possible and definitely wear masks out in public. I guess more parents are doing to be homeschooling their kids this year as they sat the omega virus doesn’t have many symptoms in children but the children are very infectious. The death rate in 25+ years old of Omega (in the most recent studies) is showing to be like the 80+ Years old death rate of the original Covid strain. And treatments are not as effective. I think that is why Fauci is out there suddenly telling us again that vaccinated people have to mask still. This isn’t over, in fact this new wave coming is absolutely terrifying. I think the news is trying to minimize it, as they have realized that the vaccines are less effective towards this newest strain and don’t want to cause mass panic.

    • Korra says:

      Sorry, but where are you getting your information? There are no news sources discussing an omega variant. And, omega is still way the Greek alphabet from the current variant names that are known. Additionally, Fauci’s comments about masking up were specific to areas with low vaccination rates, e.g. southern states or rural areas where the majority of the population have anti-vax attitudes. I am still wary of letting my guard down and believe we still have a ways to go, but fear mongering like this doesn’t help either.

  11. Cat C says:

    Glad to hear! I drove 7hrs downstate to get the J&J at the end of March. (I qualified there and very few in the area getting vaccinated.) It’s just my daughter and I now, so anything I can do to help protect us is good. She got vaccinated when they rolled out for kids but we’re still taking precautions. Living life just more mindful.
