Talk:Postnatal - Infectious Diseases School Exclusion

From Embryology

The following information is provided for educational purposes only.

These are NHMRC (2006) the recommended minimum periods of exclusion from schools, pre-schools and child care centres based on risk of infection but a child or staff member may need to stay at home longer than the exclusion period to recover from an illness. Different exclusion periods will apply to people whose work involves food handling.

Please refer to the original document.

Duration of immunity after primary series Unknown; some evidence that immunity wanes with time Variable: probably around five years; longer in presence of natural boosting or booster doses 10 years or more Unknown; wanes with time Presumed lifelong for both OPV and IPV, but unknown Lifelong in most; rare cases of waning immunity after one dose, not two Lifelong in most; presumed rare cases of waning immunity after one dose, not two Unknown, but lasts for at least three years beyond period of greatest exposure More than 15 years; further follow-up is continuing For at least 10 years and possibly for life Unconjugated wanes rapidly for children under five, more than three to five years for older children; conjugated uncertain Unknown, may be lifelong
Schedule Given at or near birth in populations at high risk Three-dose schedule recommended at 6, 10, and 14 weeks in developing countries for DTP vaccine; other schedules in common use; booster doses at 18 months and four to six years also suggested Normally given as DTP vaccine to children; unimmunized pregnant women should be given two doses of tetanus toxoid or tetanus reduced diphtheria toxoid, and a total of five doses is required to provide protection through all childbearing years Usually given in childhood as combination vaccine (DTP) OPV: four doses (birth, 6, 10, and 14 weeks) in polioendemic countries; birth dose may be omitted elsewhere with fourth dose given later; supplemental doses (up to 10) given in national campaigns for eradication; IPV: three to four doses: 2, 4, 6 to 18 months, and four to six years First dose at 9 or 12 to 15 months); a second opportunity to receive a dose of measles vaccine (either through routine [18 months or four to six years] or supplemental immunization activities) should be provided for all children First dose at 12 to 15 months; when given, a second dose with measles vaccine Three or four doses; usually given during the same visit as for DTP Several schedules: at birth, 6, and 14 weeks; with first three doses of DTP; birth dose needed if mother is a carrier and recommended if perinatal transmission of hepatitis B is frequent; four doses total can be given although only three are required One dose at 9 to 12 months with measles in countries where yellow fever poses a risk Unconjugated: one dose at two years or older and second dose three to five years later for high risk; conjugate C: three doses at two, three, and four or two, four, and six months for infants; one dose for older children and adults; conjugate A, C, Y, Wi35 currently only approved for one dose at 11 years or older Live: one year and two years; killed: days 0, 7, and 30 followed by booster two years later and then every three years
Status as of the end of 2001 158 countries using BCG; 85 percent coverage All countries; 78 percent coverage Childhood: all countries; 78 percent coverage All countries; 78 percent coverage All countries; 79 percent routine, plus supplemental coverage Routine first dose all countries, 77 percent coverage; second opportunity, 164 out of 192 countries 110 countries in 2003 89 countries; global coverage less than 18 percent 147 countries; global coverage 42 percent 29 of 43 countries at risk using vaccine; 30 percent coverage in target population European countries, Canada (and United States in 2005) Southeast Asia
Comments Reasons for varying efficacy are multifactorial, including differences in vaccines Recent trends to lower antibody levels in adults without booster doses because of waning immunity and less natural boosting Five doses in adults provide protection for more than 20 years Variability in whole cell vaccines; acellular vaccines used in some developed countries Primary series gives incomplete protection in developing countries Lower efficacy when maternal antibody present Lower efficacy when maternal antibody present None Efficacy lower if injected into fat None None None
