For most of the outbreak, until early September, Covid-19 vaccines targeted the original strain of the coronavirus, although vastly different mutants were emerging. Vaccines continue to show effective protection even against different species, and now experts hope that the new vaccines can go further and provide more protection.

Known as “bivalent” vaccines, the modified doses contain half of the original vaccine formulation and half of the immunity from the newer Omicron versions, BA.4 and BA.5.

As of the beginning of the month, about 1.5% of those eligible to receive the updated incentive have done so — a figure one infectious disease expert called “demoralizing.”

“At this point, I would expect a large percentage of Americans to be encouraged,” Dr. Scott Roberts with Yale Medicine told NBC.

As fall begins and cooler weather sets in, health officials are urging boosters to prevent another possible surgery.

“Cold weather is coming and residents are starting to go home, which is typically when respiratory virus rates increase. Please do not wait to vaccinate this year. Act now to protect yourself, your family and our entire city. Chicago Department of Public Health Commissioner Dr. Alison Arwadi said in a news release Friday.

If you’re thinking about getting the latest vaccine or aren’t sure, here’s what you need to know, including possible side effects, where vaccines are offered, and who should receive them.

What are the possible side effects?

Side effects caused by stimulants may not be different from your last dose.

“We have no information on this. [yet]Essentially giving two vaccines in one injection – but biologically, I just don’t expect the side effects, severity or safety profile of the shot to be any different than the current MRNA vaccines and boosters,” said Dr. Paul Offitt, director of the PRES. a member of the Center for Immunization Education at the Children’s Hospital of Philadelphia and the US Food and Drug Administration’s Independent Advisory Group; He told CNBC Make It..

According to the Food and Drug Administration, people receiving the bivalent vaccine “may experience adverse reactions similar to those reported by individuals who have received conventionally approved or approved monovalent mRNA COVID-19 vaccines.”

Side effects reported by study participants included:

  • Pain, redness or swelling at the injection site
  • Fatigue
  • Headache
  • Muscle pain
  • Mixing pain
  • Chilling
  • Swollen lymph nodes in the arm where the shot was given
  • Nausea or vomiting
  • Fever

The side effects were similar for both Moderna and Pfizer’s vaccines and largely mirrored the side effects expected from earlier doses.

The CDC says side effects from the third shot are similar to a “two-dose series.”

The most common symptoms include fatigue and pain at the injection site, but “most symptoms were mild to moderate.”

As with previous doses of the vaccine, the CDC says “serious side effects are rare, but they can occur.”

Who is eligible?

According to the Centers for Disease Control and Prevention, only those who have completed the full Covid vaccine series — either two Moderna or Pfizer vaccines, or one Johnson & Johnson shot — are eligible. In addition, the vaccines have certain age restrictions, which are listed below.

  • Individuals 18 and older are eligible to receive Pfizer or Moderna’s updated covid booster shot.
  • Only 12 to 17-year-olds can be given the Pfizer booster dose
  • While those under 18 are eligible for the new Covid booster, they are not eligible for the Mordana dose.

Where can I go to get the updated incentive?

Walgreens and CVS, along with several other retail chains, are among those offering updated incentives. Walgreens encourages anyone to make an appointment through the Walgreens app, by calling 1-800-WALGREENS or by visiting Online. Walk-ins are allowed regardless of appointments.

CVS encourages interested parties to make an appointment. online, As he reported on the planned news release earlier this month. At the time, CVS said initial availability of the updated incentives was limited.

Will children be eligible soon?

Moderna said on Friday that it has asked the FDA to approve the booster for children, explaining that it has filed two separate requests for approval — one for children ages 12 to 17 and one for children ages 6 to 11.

This week, the CDC said it expects to recommend updated boosters for children between early and mid-October. Pfizer notified a CDC advisory committee in early October that it plans to ask the FDA to approve the boosters for children ages 5 to 11.

The new covid vaccines, especially those designed to target the omicron variant and highly infectious sub-variants, come with many questions, including whether some will still get the boosted boost?

Can you mix and match your high shots?

Although the Centers for Disease Control and Prevention does not recommend mixing products for your main series of doses, incentives can be mixed.

Here’s the CDC’s guide to mixing and matching boosters based on which shots you already have.

  • People 18 and older may receive a different product for promotion than they receive for their main series, as long as it’s Pfizer-BioNTech or Moderna.
  • Teens ages 12-17 may receive a different product for promotion than they receive for their main series, as long as it’s Pfizer-BioNTech.
  • Children between the ages of 5 and 11 have received the Pfizer-BioNTech Primer Series and should receive Pfizer-BioNTech for encouragement.
  • People 12 years of age and older can only receive the updated (bivalent) mRNA enhancer (Pfizer-BioNTech or Moderna). You can no longer find the original (monovalent) mRNA enhancer.
  • Novavax is not approved for use as a booster dose at this time.
