1 There has been some chatter that while well-intended, keeping the original strain in the bivalent booster did more harm than good.
2 The recommendation is sparking debate on whether or not bivalent shots were effective in the first place — and if the world is ready to move on from boosting immunity against the original strain.
3 Yet only about 43 percent of adults 65 and older have received a bivalent booster shot so far.
4 This is a switch from the current formula, which is bivalent, targeting both the spike protein from the ancestral SARS-CoV-2 strain and the previous leading omicron subvariants BA.4/5 (which share a spike protein).
5 Statewide, just under 46% of those 65 and older who have been vaccinated have also gotten a bivalent booster.
6 The bivalent booster is formulated to protect not only against the original coronavirus strain, but also the Omicron subvariants that dominated the nation throughout much of the year — namely BA.5.
7 For now, older adults or those with weak immune systems will be eligible for two or more bivalent doses.

9 Objective To construct a bivalent VP1 gene vaccine against Coxsackie virus B1 and B3 (CVB1 and CVB3) and to test its immunogenicity in mice.
目的构建柯萨奇病毒(CV)B1/B3型二价VP1基因免疫质粒,并探讨其免疫原性。
10 The bivalent vaccines rolled out last fall as a booster dose and consist of half the original recipe and half protection against the BA.4 and BA.5 versions of omicron.
11 As bivalent boosters rolled out last year, the Florida health department’s homepage removed information on covid vaccines.
12 "The bivalent booster did not seem to be very effective for preventing severe disease among those who are 18-64 years old."
13 In partnership with the Finlay Institute in Cuba, Bio-Manguinhos is working with WHO to ensure a supply of up to 10 million doses of bivalent ac meningitis vaccine by the next epidemic season.
与古巴的芬莱研究所合作,Bio - Manguinhos正在与世卫组织合作,确保在下一个流行季节之前供应多达1000万剂二价AC群脑膜炎疫苗。
14 Only about 42 percent of people 65 and older have received the first bivalent booster, according to the CDC.
15 Using Agrobacterium vacuum infiltration method the plant bivalent expression vector pBI121 containing GUS as a report gene was transformed into lettuce Lactuca sativa l.
以GUS基因作为报告基因,利用农杆菌真空渗透法,采取正交试验设计对莴苣LactucasativaL。
16 Those with weakened immune systems may do so two months after their previous bivalent dose, and may choose to receive more doses in consultation with their health care provider.
17 If persons follow through on their eagerness, uptake of the latest booster would exceed the use of the “bivalent” booster that was offered in the fall of last year.
18 “The FDA continuously and rigorously monitors data regarding the use of the monovalent and bivalent COVID-19 vaccines and all the data shows that the vaccines are safe,” Capobianco said in a statement.
19 Regardless of the brand, the bivalent booster is formulated to protect against the hyper-infectious family of Omicron coronavirus subvariants that have dominated the nation for more than a year.
20 But the first shots do little to protect from current strains, and just 70% of residents and 48% of staff have had the bivalent booster.
