What’s Up with Intranasal Covid-19 Vaccines?

I saw the JAMA article on intranasal vaccines research for Covid-19. It starts off pretty supportive of the principle. However, at the bottom of the article, the outlook looks pretty stable for injectable vaccines for at least a good long while.

It’s an interesting read. Skip to the Many Questions section:

How these experimental mucosal vaccines stack up against mRNA vaccines, considered the standard of care, remains to be seen, Beigel noted. The NIAID intends to conduct phase 2 trials that would compare mucosal and mRNA vaccines head-to-head, “so you’d know for certain what you’re trading off,” he said.

Ideally, a mucosal vaccine would generate as good a systemic immune response as an mRNA vaccine as well as a robust mucosal immune response. But an excellent mucosal immune response might make up for a bit of a decline in the systemic immune response, Beigel explained. Perhaps a vaccine inhaled through the mouth and into the lungs could provide the best of both worlds—strong mucosal and systemic immunity—but there are no data yet to support that theory, he said.

“Everyone knows we need a better vaccine and would really like it if we could get something that interrupts transmission and stops even mild disease,” Beigel said. “Whether that’s attainable or not, we don’t know.”

I’m not knocking the concept by suggesting you read the Conflict of Interest Disclosures.

Moderate Respiratory Illness Activity in Iowa

The CDC tracks respiratory illness and there is moderate activity in Iowa according the data tracker.

The weekly snapshot as of December 1, 2023 shows highlights including:

  • “COVID-19 test positivity (percentage of tests conducted that were positive), emergency department visits, and hospitalizations have increased nationally. A group of Omicron variants (XBB and its sublineages) are the predominant lineages detected in the U.S., with HV.1 being most common. The prevalence of another lineage, BA.2.86, is projected to account for 5-15% of currently circulating variants. CDC continues to monitor HV.1, BA.2.86, and all other lineages.
  • National test positivity, emergency department visits, and hospitalizations for influenza continue to increase.
  • RSV emergency department visits and hospitalizations continue to increase across the country. RSV-associated hospitalization rates remain elevated among young children and are increasing among older adults; of note, only 14.8% of adults 60+ report having received an RSV vaccine.
  • National vaccination coverage for COVID-19, influenza, and RSV vaccines increased less than one percentage point for children and adults, where indicated, compared to the previous week and remains low for both groups.
  • CDC has been monitoring increases in respiratory illness reported recently among children, including potential elevated rates of pediatric pneumonia in parts of the United States. These reported increases do not appear to be due to a new virus or other pathogen but to several viral or bacterial causes that we expect to see during the respiratory illness season. CDC will continue to work closely with our state and local public health partners to maintain strong situational awareness and will provide updates, as needed.”

CDC Update on Covid-19 Variant BA.2.86

I saw a news item headline which mentioned Covid-19 Variant. BA.2.86. The CDC website tracking respiratory variants has a definitive update as of November 27, 2023:

“What to know about BA.2.86

  • The virus that causes COVID-19 is constantly changing over time. Sometimes these changes allow new variants to spread more quickly or effectively. If that occurs, the new variant may become more common relative to other variants that are circulating.
  • Since CDC’s first post on BA.2.86 in August 2023, the proportion of infections caused by BA.2.86 has slowly increased. In the CDC Nowcast posted Nov. 27, 2023, BA.2.86 is projected to account for 5-15% of currently circulating variants.
  • CDC projects BA.2.86 and its offshoots like JN.1 will continue to increase as a proportion of SARS-CoV-2 genomic sequences.
  • At this time, BA.2.86 does not appear to be driving increases in infections or hospitalizations in the United States.
  • CDC contributed to and agrees with the World Health Organization’s recent risk assessment about BA.2.86 suggesting that the public health risk posed by this variant is low compared with other circulating variants, based on available limited evidence.
  • Updated COVID-19 vaccines are expected to increase protection against BA.2.86, as they do for other variants.
  • As mentioned in previous updates, COVID-19 tests and treatments are expected to be effective against this variant, including its offshoot JN.1.
  • It is not possible at this time to know whether BA.2.86 infection produces different symptoms from other variants. In general, symptoms of COVID-19 tend to be similar across variants. The types of symptoms and how severe they are usually depend more on a person’s immunity than which variant causes the infection.
  • Regardless of what variants happen, CDC will continue to track them, working closely with partners around the world to understand how they are spreading and how they respond to vaccines and treatments.”

CDC Educates About Covid-19 Variants

Sometimes I see news about Covid-19 variants. They typically sound alarming. The CDC has posted an update on Covid-19 variants that is reassuring. There will always be variants. Not all will be serious threats. According to the update:

“While new variants like BA.2.86 and JN.1 attract attention, right now, 99 percent of SARS-CoV-2 variants are part of the XBB group of the Omicron variant, which is what this year’s updated vaccines are based on. CDC is continuing to track the spread and impact of BA.2.86 and JN.1, as well as other variants as they come and go.

For as long as we have COVID-19, we’ll have new variants. Nearly all represent relatively small changes compared with previous variants. CDC and other agencies monitor for impacts of new variants on vaccines, tests, and treatments, and will alert the public quickly if anything concerning is detected. Most of the time, new variants make little to no impact.

Regardless of the variant, all SARS-CoV-2 viruses spread the same way. So it’s important to protect yourself and others by staying up to date with COVID-19 vaccines, improving ventilation and staying home when you’re sick.”

CDC Update on Respiratory Viruses and the Covid-19 Vaccine

CDC posted an update on Covid-19 vaccination on October 13, 2023. In brief, the salient points:

They save lives and prevent hospitalizations.

The vaccines work.

The side effects are mild or moderate.

Scientific evidence supports the safety and effectiveness of the vaccines.

They don’t make you magnetic and they don’t have microchips to track your movements. We’re not living in an X-File episode.

CDC Recommendations for Fall-Winter Immunizations

The CDC recommendations for Fall-winter immunizations were updated as of September 29, 2023. A few states require a physician’s prescription for the RSV vaccine. Information varies on the web on which states require a prescription for the RSV vaccine. The Iowa Board of Pharmacy website is clear on the matter–you’ll need a prescription.

Most states don’t require a prescription for the RSV vaccine. The CDC recommends having a shared decision-making discussion with your doctor to help you decide about whether the RSV vaccine is right for you. The best thing to do would be to call your doctor, the state board of pharmacy, or your local pharmacy to find out how you should proceed.

Covid-19 and Flu Vaccines Today

Today I got the new Covid-19 vaccine and the flu shot. I scheduled on line late last week and got right in. I didn’t have to wait long in line—and there were others getting the same vaccines. Sena will get them tomorrow.

It’s up to you.

COVID-19 in the Rearview Mirror?

One way to think about the Covid-19 pandemic can be that it’s in our rearview mirror, which is one way of saying it’s behind us now.

On the other hand, another way to think about it is that COVID-19 is in our rearview mirror because it’s tailing us.

So, we can’t keep staring in the rearview mirror because that’s not a safe way to drive. We can look forward and drive, paying attention to the signs, which guide us on how to stay ahead of and outrun another pandemic.

One way to do that is to bookmark the CDC COVID-19 web site.

How to Find Covid-19 Vaccine Availability By County

I’m finding out that maybe the best way to learn what the local public health issues are concerning Covid-19 infections as well as vaccine availability are through the county public health agency in my area.

According to the Johnson County Public Health department, hospital admission rates in Johnson County currently low. I can search the map and see that admissions are rising in certain areas of Iowa.

I also learned that the new Covid-19 vaccine will more likely be available closer to the end of the month or early next month rather than in a few days as suggested by presenters at the CDC meeting on September 12, 2023.

The county public health agencies may not have the most current information. Johnson County’s last update as of yesterday was September 1, 2023.

You can also check local pharmacies for availability of the Covid-19 vaccine.
