Is typhoid a pregnancy risk?
Both the oral and parenteral typhoid vaccines are classified as FDA pregnancy risk category C. There are no adequate, well controlled studies in pregnant humans; animal reproduction studies have not been conducted. It is not known if administration of the vaccine can cause fetal harm or affect the reproductive system. [43467] [43468] In general, live, attenuated vaccines like the oral typhoid vaccine should be avoided in pregnancy unless urgently needed, due to a theoretical risk to the fetus. No evidence exists of risk to the fetus from vaccinating pregnant women with inactivated bacterial vaccines; however, use is usually reserved for when the likelihood of disease exposure is high, an infection would pose a risk to mother or fetus, and when the vaccine is unlikely to cause harm. [43236] Typhoid vaccine should be used during pregnancy only if the potential benefit to the mother justifies the potential risk to the fetus. According to FDA-approved labeling for injectable typhoid vaccine, delaying vaccination until the second or third trimester may be a reasonable precaution to minimize the possibility of teratogenicity. [43467]
Can you give abatacept with live shots?
Abatacept: (Contraindicated) If possible, administer all needed vaccines before abatacept initiation. Live vaccines should not be given concurrently with abatacept or within 3 months of its discontinuation. The immune response of the immunocompromised patient to vaccines may be decreased and adjusted doses or boosters that are more frequent may be required. The immune response to an inactive vaccine may still be suboptimal. Live virus vaccines may induce the illness they are intended to prevent and are contraindicated for use during immunosuppressive treatment. If immunization is necessary, choose an alternative to live vaccination, or, consider a delay or change in the immunization schedule. Practitioners should refer to the most recent CDC guidelines regarding vaccination of patients who are receiving drugs that adversely affect the immune system.

They also include an update on the epidemiology of enteric fever in the United States, focusing on increasing drug resistance in Salmonella enterica serotype Typhi, the cause of typhoid fever, as well as the emergence of Salmonella serotype Paratyphi A, a cause of paratyphoid fever, against which typhoid vaccines offer little or no protection.

What is ty21a?
Ty21a is an orally administered, live-attenuated vaccine derived from S. Typhi strain Ty2. This attenuated strain was constructed by non-directed mutagenesis using a chemical mutagen and ultraviolet light; it has a galactose-epimerase (galE) mutation, which results in partial loss of lipopolysaccharide that was proposed to be the basis for reduced virulence. It was isolated in 1975, initially tested in Egypt in 1980 [122], and first licensed in 1989. Bhutta et al. [119] reviewed four efficacy trials, done mostly with children aged 6 years and above, in Egypt, Chile and Indonesia. Normally, three doses were given two days apart over a five-day period. Ty21a was shown to have the following protective efficacy rates against blood culture-confirmed typhoid fever after three years of follow-up: 33–67% where enteric coated capsules were used; 53–96% where a liquid formulation was used. Ty21a was considered to provide a degree of protection for at least 5–7 years, especially if four doses of the vaccine are used rather than three [129,120]. It has been noted that the extensive chemical mutagenesis used to construct the strain may have eliminated some gene functions necessary for its optimal immunogenicity, and that the galE and via mutations in Ty21a may not contribute greatly to its attenuation [123]. Thus there have been efforts to construct attenuated strains in which the nature of the genetic changes is better understood (described below).
What is the name of the strain of Typhi?
S. Typhi strain Ty21a that is currently manufactured under the commercial name Vivotif®, was derived from the wild-type strain Ty2 by two rounds of nitrosoguanidine (NTG) chemical mutagenesis.

The capsules need to be swallowed intact so that the contained liquid suspension of live bacteria passes undisturbed through the acid milieu of the stomach. In many countries, but not the United States, a lyophilized preparation that is reconstituted in water is available in a three-dose regimen for children >3 years.
How often should I take a repeat shot of a syringe?
Unlike the injectable, use of the oral vaccine may result in nonadherence and a suboptimal response due to self-administration at home by the traveler.60 A repeat full three-dose or four-dose series is advised every 3 or 5 years (varies by schedule and national labeling) for persons with continued or repeated exposure.
How many days of typhoid shot?
